Lipomas are benign, well-circumscribed radiolucent masses (Figs. 4.1, 4.2, 4.3, 4.4, 4.5). Clinically, lipomas are either nonpalpable or, if palpable, soft and freely mobile. Lipomas are visualized more easily in an otherwise dense, glandular breast because of the difference in density In terms of sonographic features suggestive of benign breast lesions, a well circumscribed margin has a positive predictive value for being benign about 90% of the time. Also, an 'oval shape' indicates a benign lesion about 84% of the time. Breast lesions with a 'parallel' orientation are predictive of benignity almost 80% of the time
Irregular hypoechoic masses in the breast do not always indicate malignancies. Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Some of these diseases such as inflammation and trauma-related breast lesions could be suspected from a patient's symptoms and personal history Physical Examination. • Left breast: 3 cm lump in the upper outer quadrant. • Right breast: normal exam. Mammogram. Mass ( Fig. 5.1) • Margin: circumscribed. • Shape: oval. • Density: fat-containing. Fig. 5.1 In the upper outer quadrant of the left breast, there is a well-defined oval mass 72 F with history of colorectal cancer and palpable breast mass with abnormal uptake on PET: Mammogram: Oval mass in the retroareolar region. Ultrasound: 35 x 18 x 32 mm hypoechoic mass with internal vascularity at the palpable abnormality. PET/CT: Circumscribed 3 cm right breast mass with increased F18-FDG uptake
Benign masses are often round or oval with circumscribed margins. Malignant lesions tend to have irregular, indistinct, or spiculated margins. Malignancies tend to have density greater than that of.. The mammographic appearance of intracystic papillary carcinoma is that of a round or oval well-circumscribed mass, and satellite nodules or microcalcifications are occasionally seen (7, 12) (Fig 1a). At breast US, intracystic papillary carcinoma manifests as a solid or complex mass with posterior acoustic enhancement (7) (Fig 1b) On mammography PASH typically presents as a non-calcified oval mass or as a developing focal asymmetry (Figure 4e). 37 On ultrasound it most commonly presents as a well-circumscribed oval hypoechoic mass. 36,37 Histologically PASH is characterized by slit-like spaces in the stroma lined by spindle-shaped myofibroblasts Mammography shows an oval-shaped mass containing zones of fat, while ultrasound reveals a well-circumscribed, homogeneous, hypoechoic (67%), isoechoic (20%) or hyperechoic (13%) oval-shaped mass. Lactating adenoma usually resolves spontaneously after stopping breastfeeding An echogenic breast mass is defined as a lesion that is hyperechoic in comparison with subcutaneous adipose tissue at ultrasonography (US), in accordance with the US lexicon of the Breast Imaging Reporting and Data System (BI-RADS) of the American College of Radiology ( 1 ). At sonography, only 0.6%-5.6% of breast masses are echogenic ( 2.
At mammography, phyllodes tumor manifests as a large, well-circumscribed oval or lobulated mass that may have a radiolucent halo (, 36) (, Fig 15). Coarse, plaquelike calcifications are rarely seen. At US, an inhomogeneous, solid-appearing mass is the most common manifestation Palpation reveals a well-circumscribed, firm mass in the lower-outer quadrant of the left breast. The mass is non-tender, movable, and its margins are easily distinguished. Estimated size of the mass is 1.5-2.0 cm in diameter. Compression of the nipples reveals no discharge Cystic lesions of the breast may present in women of any age but are most common between 30 and 50 years of age ( Table 1 ). They may be detected incidentally on screening mammography or present with such signs and symptoms as nipple discharge or a palpable mass. On mammography, a cystic lesion appears as a round, oval, or lobulated mass with. A circumscribed mass in mammography is a mass where the contour is clearly defined along at least 75% of its surface. The remaining 25% may, at most, be masked by the adjacent gland. Circumscribed masses first indicate benign lesions. Beside above, what is a hypoechoic mass in breast The ultrasound signs of breast masses are explained by the histopathological data. The shape and the margin of a mass depend on its histological type and its tissue composition. In practice, in ultrasonography there are two major groups of breast masses: round or oval masses and irregularly shaped masses. Round and oval masses Fibroadenom
Ultrasound showed a well-circumscribed oval-shaped mass, measuring 5.7x3.3cm, in parallel orientation to the skin with hyper-echoic and hypoechoic tissue components and showed no internal vascularity on colour Doppler. No suspicious axillary lymph nodes Well Circumscribed Cystic Lesions. The most common clinical differential diagnosis of cystic orbital lesions includes dermoid cyst, colobo-matous cyst, teratoma, meningoencephalocele, lymphangioma, acquired inclusion cyst, chronic hematic cyst (cholesterol granuloma), mucocele, subperiosteal hematoma, and parasitic cyst.25 On MRI these lesions. The BI-RADS® Lexicon ( 2) defines mass shapes as round, oval, lobular, and irregular and mass margins as circumscribed, obscured, microlobulated, indistinct, and spiculated. Indistinct masses are those in which a lesion or portion of the margin is fuzzy or poorly defined ( Fig. 5.1 ). The shape of an indistinct mass may be any of those listed. On BUS, a well-circumscribed solid oval hypoechoic or heterogeneous mass may be seen; however, occasionally it is seen as an echogenic mass. 3, 4 Though it is benign in etiology, excision may be.
Well circumscribed mass, infrequently associated with tenderness and nipple discharge Diagnosis on core biopsy specimen can be challenging Presence of tightly aggregated glands arranged in compact nodules and prominent clear cell or spindle cell myoepithelium are clues to the diagnosis ( Breast J 2004;10:522 Lisa Jacobs, M.D., Johns Hopkins breast cancer surgeon, and Eniola Oluyemi, M.D., Johns Hopkins Community Breast Imaging radiologist, receive many questions about how to interpret common findings on a mammogram report.The intent of the report is a communication between the doctor who interprets your mammogram and your primary care doctor. However, this report is often available to you, and you. Sonogram of palpable abnormality shows well-circumscribed oval homogeneous mass consistent with fibroadenoma. View larger version (83K) Fig. 3A — 45-year-old woman with extensive lobular carcinoma of left breast
Additional US of the mass: Concordant with the lump and the mass on the mammogram there is an oval simple cyst, parallel orientation, circumscribed, Anechoic with posterior enhancement. Size : 3,5 x 1,5 cm. In the right breast at least 2 more smaller cysts. Assessment BI-RADS 2 (benign finding). The palpable mass is a simple cyst Hypoechoic mass in breast ultrasound - In ultrasound, a benign breast mass usually has a well-defined and fine margin. Lesions will also be micro-droplets, or only two to four mild small leaves. Benign breast lesions are also oval or circular and often tend to be wider than height (which indicates a parallel direction to the chest wall) Oval or lobulated mass weigh well circumscribed borders Lactational Adenoma typically occur In the peri partum period( late in pregnancy) and are on of the most prevalent breast lesions during post partum perio well-circumscribed oval mass, indistinguishable from fibroadenoma No cellular atypia lactating adenoma also resemble fibroadenoma clinically and radiographically mean 25 yo presents during pregnancy or lactation commonly macrolobulated, well circumscribed, hypoechoic mass with posterior acoustic enahncemen Mass size and tenderness influenced by estrogen levels: Increased size: pregnancy, lactation, pre-menstruation, and oral contraceptives; Regresses after menopause; Diagnosis: US: well-defined solid mass, regular boundaries, and a weak echo signal; Mammogram: Well-circumscribed oval mass, may have lobulation
Right breast ultrasound showed an oval well-circumscribed mass with mixed echogenicity in the 11:00 position 6 cm from the nipple, measuring 2.3×1.1×2.3 cm 3 with minimal internal vascularity and soft elastography characteristics; categorized BI-RADS Category 4 . Clinical exam demonstrated a 3 cm firm, irregular mass in the upper outer. The breast tissue is heterogeneously dense, which could obscure the detection of small masses. The overall nodular parenchymal pattern in both breasts is stable. There are multiple unchanged circumscribed masses over serial exams in each breast. There is an unchanged oval well-circumscribed 1.2 x 0.8 cm mass in the 12:00 position left breast. Breast u/s: well circumscribed hypoechoic solid nodules slightly lobulated wider than taller 2cm x 1cm and 0.84cm x 0.47cm means?? Dr. Michael Gabor answered Diagnostic Radiology 33 years experienc However, spot mammography confirmed a round well-circumscribed high-density mass in the axillary area. Ultrasonography showed a 1.4-cm oval-shaped, well-circumscribed echoic mass corresponding to the axillary lesion on physical examination and mammography
Oblique mediolateral mammography of left breast that shows multiple superficial nodules, oval, isodense and well-circumscribed. Close-up picture of some nodules seen on mammography where the small hypodense areas within, round and oval shape and well-circumscribed margin are shown better A well-circumscribed, oval hypoechoic mass with a major axis of 25 mm was observed in the right axilla on ultrasound (A). Contrast-enhanced CT scan revealed a mass with a well-defined contrast effect on the right axilla near the upper arm (white arrow) (B) Explanation: The large mass in the right breast at 9:00 is a breast hamartoma, also known as a fibroadenolipoma. This benign mass has the characteristic breast within a breast appearance on mammogram, which is a well-circumscribed oval mass composed of normal fibroglandular and adipose tissue. These are benign malformations and do not. A breast lump could also be a simple cyst which, being fluid-filled, has an anechoic, rather than a hypoechoic, center surrounded by a well-defined wall. Again, this is a benign, or non-cancerous, mass and can be treated by draining the contents using a needle
Breast Ultrasound. Ultrasound (US) uses sound waves to detect the features of fibroadenomas in women younger than 35 years of age. US easily differentiates solid from the cystic masses. On US, a fibroadenoma is typically seen as a well-circumscribed, round to ovoid, or macrolobulated mass with generally uniform hypoechogenicity Breast hamartomas comprise about 0.7-5% of all benign breast masses, and their main characteristic is the variety of tissue they contain [].Myoid hamartoma is a rare benign lesion of the breast, and is considered a variant of mammary hamartoma [].It was described for the first time in 1973 by Davies and Riddell [].According to some reports, this lesion is well-circumscribed and shows oval or. Solitary oval, well-circumscribed mass lesion in the right breast. b T2w MIP: high signal intensity (water content) of both lesions. c T1w precontrast slice image (left): well-circumscribed, lobulated, homogeneously hypointense lesion with peritumoral border of fat-equivalent signal intensity ( halo sign ) IDC is the most common (75%) breast cancer, presenting as an asymptomatic screen detected or palpable mass +/-nipple discharge. 3,4 At US, it is classically a hypoechoic mass with non-circumscribed margins; however, in 2% of cases it may be hyperechoic. 3,4,17 Echogenic breast masses on sonography with mammographic features such as interval.
Sonogram of the left breast demonstrating a hypoechoic well-circumscribed oval mass measuring 80 mm (longitudinal axis), with low flow vascularity detected by Doppler imaging (d). Craniocaudal (CC) breast mammogram of the right breast with increase in density, which decreased the sensitivity of mammography (e) The most common radiologic characteristic is a well-circumscribed and compressible oval mass that is composed of predominantly hyperechoic fat . The most common benign diagnosis of male breast mass is gynecomastia, which is typically diagnosed on mammogram as retroareolar fibroglandular breast tissue The pathognomonic mammographic appearance is a circumscribed mass that consists of both soft tissue and lipomatous elements surrounded by a thin radiolucent zone (Figure 3A). 8, 9 The sonographic findings are variable, but a well‐circumscribed oval mass with heterogeneous echogenicity from an accessory breast is usually seen (Figure 3B) Sonograms showed masses with an oval (n = 2) or irregular (n = 1) shape, partially microlobulated (n = 2) or well‐circumscribed (n = 1) margins, and a hypoechoic (n = 2) or an isoechoic (n = 1) internal echo texture. Sonographic assessments were classified as Breast Imaging Reporting and Data System category 4 in all 3 cases

Dr. Warren Wolfe answered. 58 years experience Family Medicine. No easy answer: It is imperative that you talk with the physician who took care of you. There are many possibilities and I would have to. At CT, fibroadenomas appear as well-circumscribed, round, or oval masses that may demonstrate coarse popcorn-like calcifications. 32 FDG PET provides a high accuracy in the differentiation of fibroadenomas from malignant tumors because fibroadenomas usually show no or mild FDG uptake Breast hamartoma is a well-circumscribed breast lesion with varying amounts of fat, epithelial and fibrous tissues. It may present as a painless, soft breast lump, similar to a fibroadenoma. Pseudocyst is a cerebrospinal fluid (CSF) pseudocyst in the breast. It is an extremely rare condition which has been known to produce a breast lump An obscured mass is a mass with greater than 25% of its margin hidden by surrounding fibroglandular tissue on mammography; hence, it cannot be fully assessed. This term is commonly used when the portion of the margin that is visualized is circumscribed and it usually implies a lower likelihood of malignancy. If the portion of the visualized margin is microlobulated, indistinct, or spiculated.
I too was just told I have a 6mm nodule in my left breast. I am 48 years old and have had yearly mammograms since I was 40. My sister was diagnosed with breast cancer at the age of 40 last year and had a double mastectomy. We do have a family history and because of this I am considered high risk and receive yearly MRI's and mammograms Can be used with palpable masses of the extremities, abdominal, chest wall, breast, etc. Oval, well to poorly marginated solid soft tissue mass with variable echogenicity may be poorly defined or well circumscribed Firm, glistening white, gritty and coarsely trabeculated cut surface resembling scar tissue A mass was excised from the. Breast cysts are round or oval structures filled with fluid. About 25% of all breast masses turn out to be cysts. Most breast cysts are benign and do not increase your risk of breast cancer. They can be very tiny, or they can be large enough to feel through the skin or see on an imaging test (a grossly evident cyst, or gross cyst) Breast ultrasound: Ultrasound can be used to make a measurement of a breast tumor, but it has been found to underestimate tumor size and is considered less accurate than mammography. Breast MRI : While a mammogram may find your lump, an MRI might be needed to measure it if your breast tissue is dense or your biopsy shows that the mass is larger.
Breast ultrasound shows a 4.0 cm hypoechoic, oval, circumscribed mass at 4 o'clock. The mass was first noted five years prior and is stable in size. Gross examination of the excised mass reveals a well-circumscribed lesion with a tan-yellow, vaguely lobulated cut surface The margin of the mass usually will be sharply de- fined in a benign lesion such as a fibroadenoma or a cyst, but a mass with this appearance may be malignant in about 7% of cases. An intramammary lymph node is usually well circumscribed, smaller than 1 cm in size, and most often seen in the upper outer quadrant of the breast A) OML mammography shows an oval well-circumscribed mass with radiolucent fat interchanged with dense fibroglandular tissue, located in the inferior quadrants of the left breast. B) Sagittal T2-weighted MR image. A heterogeneous hyperintense mass with well-defined margins is shown Neither significant past history of breast diseases nor other medical problems were stated. Physical examination revealed a well-circumscribed, 4.5 x 3.5 cm, painless, rubbery mass in the upper central aspect of the left breast. On Ultrasonography, the lump was fairly well-outlined with complex scattered echogenic areas of calcifications. Th male breast cancer parallels that of breast cancer in women, showing an irregular high-density mass with spiculated margins and with or without associated suspicious calcifications.7 On ultrasonography, myofibroblastoma is seen to typically present as a well circumscribed, round to oval, hypoechoic heterogeneous mass
On ultrasonography, the left breast mass was a well-circumscribed, oval, hypoechoic lesion measuring approximately 7 × 6 × 5 cm in size, parallel to the skin and showing increased posterior transmission Initial post-surgical baseline mammography demonstrates well-spaced titanium clips in a well-circumscribed, oval, equal density mass. Over the course of follow-up, the expected evolution of findings on mammography is a decrease in size of the oval mass with less space noted between the titanium marker clips A, B. Breast ultrasound images show well circumscribed, oval-shape hypoechoic masses in superficial area of right breast (A) and in middle of left breast (B), suggesting metastasis. C, D. Contrast enhanced abdomen CT scan shows ill-defined low density mass in pancreatic head (arrow in C ) with multiple liver metastases (D) Imaging Findings: Mammography in the craniocaudad and mediolateral oblique planes demonstrated a well-circumscribed, equal-density oval mass measuring approximately 2.5 cm at 12:00 in the left breast at the site of the palpable lump indicated by a metallic BB marker (Image 2) right breast mass. Ms. CC is a 30-year-old female at 7 months gestation presenting with a new right breast mass. She first noticed the mass two weeks ago. She denies pain, Well-circumscribed, oval mass containing one calcification. * Lactating adenoma. Lee, Sheila S., et al. The Management of Breast Symptoms in th
Clinical presentation: painless breast mass [9]. Mammography: oval or round, isodense well-circumscribed mass [10-12]. Sonography: typically well-circumscribed, homogeneously hyperechoic mass with smooth margins, without manifestation of shadowing or posterior acoustic enhancement [10-13] Breast mammogram may be helpful in the diagnosis of fibroadenoma. On breast mammogram, fibroadenoma is characterized by a well circumscribed, discrete, oval mass that is isodense to breast glandular tissue. The mass may contain coarse, popcorn calcification. Other Diagnostic Studie Pseudoangiomatous stromal hyperplasia. A 41-year-old woman presented with a palpable breast mass. Mediolateral oblique mammogram (a) shows a high-density well-circumscribed mass (arrow). Longitudinal grayscale ultrasound (b) shows a large, oval circumscribed mass. Core needle biopsy showed pseudoangiomatous stromal hyperplasia (PASH) BREAST PATHOLOGY Sonographic Characteristics of Common Lesions. Mass. Characteristics. Simple cyst. Oval or round, anechoic, imperceptible capsule, posterior acoustic enhancement, edge refraction shadowing, often compressible. Fibrocystic changes. Multiple cysts, well circumscribed, thin walls, increased fibrous stroma.
Breast hamartomas have become more frequently diagnosed due to the increased use of mammography, but they may be mistaken for neoplasms . During mammography scans, hamartomas are identified as typically well-circumscribed, round to oval masses containing fat and soft tissue densities with a thin, radiopaque pseudocapsule Fibro adenomas are the most common solid breast masses excised in the adolescent population [1]. Classically, fibro adenomas are mobile non-tender breast lesions [1]. US scans show the typically benign features of benign solid lesions: a well-circumscribed hypo echoic mass that may be oval, round, or macro lobulated Typical adult fibroadenomas are well circumscribed, hypoechoic, oval or round, macrolobulated (not more than three lobulations) masses with transverse dimension larger than anteroposterior.13 Juvenile giant fibroadenomas may not conform to most of these features. Rapidly enlarging breast mass is a suspicious feature and requires histopathology. What Is isoechoic? The term isoechoic refers to a similar pattern in which echoes are heard, usually between two or more neighboring masses of tissue. Isoechoic conditions are generally picked up by ultrasounds. There are many different types of cancers in which the masses have isoechoic tendencies, or when the masses are so close to each. Simple Cysts • Mammographic findings: - Circumscribed round or oval mass. • Ultrasound: - Sonographic criteria set forth by Stavros: • Anechoic. • Well circumscribed with a thin echogenic capsule. • Increased through-transmission. • Thin edge shadows. - BI-RADS 2 28
Bx unless stable or diffuse bilateral. Round calcifications are typically always benign and do not need follow-up or biopsy. False. On 1st screening mammogram, BIRADS 3. If new or increasing, must BIOPSY. Coarse heterogeneous calcifications must be biopsied unless they are stable. DDx = fibroadenoma, fibrosis, dystrophic, and BrCa Most well-circumscribed breast masses are benign lesions such as cysts, fibroadenomas, and intramammary lymph nodes. Nevertheless, 10%-20% of breast malignancies are well-circumscribed masses, and these malignancies include papillary, mucinous, medullary, and metaplastic carcinomas, as well as malignant phyllodes tumors. Therefore, it is important to differentiate these well-circumscribed. The most common well-circumscribed carcinoma of the breast is: a. infiltrating ductal carcinoma. b. mucinous carcinoma. c. papillary carcinoma. d. lobular carcinoma. e. colloid carcinoma. f. medullary carcinoma . 40.1994, 1993 . What is the risk of carcinoma in a well-circumscribed mass which is less than 1 cm in diameter? a. 2%. b. 5%. c. 10%.
