Objective. Imaging of the male breast is most often performed for the evaluation of a clinical abnormality such as breast enlargement or tenderness, a palpable mass, nipple skin changes, or nipple discharge. Most breast lesions encountered in men are benign. Malignant breast lesions are less frequent; breast cancer accounts for less than 1% of all male cancers in the United States. The initial imaging evaluation of a finding in the male breast is performed with mammography. Sonography is frequently used as an adjunct to mammography but is less often used as the primary imaging modality. The objective of this article is to provide readers with a thorough review of the sonographic appearances of benign and malignant male breast disease. Methods. We reviewed our institution's case database to identify male patients who underwent mammography, sonography, and subsequent biopsy of a breast lesion. These cases were collected and reviewed to select the best imaging examples. Results. A spectrum of benign and malignant male breast disease is presented with corresponding sonographic, mammographic, and pathologic imaging. For each entity, the salient imaging findings and typical clinical presentation are discussed. Conclusions. Most studies in the literature have reported on the mammographic and sonographic imaging features of primary breast carcinoma in men. However, very little has been reported on the sonographic appearance of benign and malignant male breast conditions. Recognition and correct identification of pathologic male breast entities on sonography is essential to determine appropriate management recommendations and avoid unnecessary biopsies.  相似文献

Objective. The purpose of this study was to assess the utility and efficacy of second‐look breast sonography in the evaluation of abnormalities identified on presurgical breast magnetic resonance imaging (MRI) examinations. Methods. A retrospective review was performed of 152 presurgical breast MRI examinations having 196 unsuspected abnormalities to identify findings that underwent subsequent breast sonography. Eligible examinations had a suspicious abnormality identified on presurgical MRI and documentation of the location and size of the finding on MRI and subsequent second‐look sonography. Fourteen examinations not meeting the criteria were excluded, with 182 abnormalities remaining. Patient medical records were reviewed. Results. Seventy percent (128 of 182) of breast MRI lesions were visible at second‐look sonography; 30% (54 of 182) were sonographically occult. Ninety‐five percent (121 of 128) of sonographically visible abnormalities underwent breast biopsy. Pathologic examinations of sampled sonographically visible lesions revealed 39 cancers, 9 high‐risk lesions, 72 benign lesions, and 1 lesion not specified at surgery; 23% (9 of 128) of cancers were in the contralateral breast. Fifty‐four lesions were sonographically occult. Needle biopsy was performed for 93% (50 of 54) of occult lesions, revealing 8 cancers, 1 high‐risk lesion, and 41 benign lesions; 3 of the benign lesions did not have sufficient pathologic specimens but were benign at follow‐up. Magnetic resonance imaging guidance was used in 86% (43 of 50) of these biopsies. One contralateral cancer was identified in the sonographically occult subset. Of the 182 lesions that underwent second‐look sonography, 20% (36 of 182) had a change in management. Conclusions. Second‐look sonography has value in the evaluation of abnormalities found on breast MRI. We found enhancements in 70% (128 of 182), yielding 39 cancers.  相似文献

PURPOSE: The objective of this study was to examine the diagnostic accuracy of sonographically guided 14-gauge core-needle biopsy (CNB). METHODS: Sonographically guided 14-gauge CNBs of 715 breast lesions were performed in 652 patients. Histopathologic results were correlated with imaging findings, and repeat biopsy was recommended in the cases of discordance between the radiologic and pathologic results. Long-term follow-up was used for patients with CNB findings of a benign lesion. RESULTS: Sonographically guided CNB revealed malignancy in 311 lesions (43%). Thirty-one lesions with CNB findings indicating benign conditions underwent additional image-guided or excisional biopsy because of indeterminate pathologic features, disagreement between radiologic and pathologic results, surgeon preference, or patient request. Within these 31 cases, 9 malignancies were diagnosed. The duration of follow-up for the remaining 373 benign lesions varied from 27 to 60 months. In 3 of these 373 cases, carcinoma was diagnosed at the site of CNB. The false-negative rate of 14-gauge sonographically guided CNB was 3.7%, and the sensitivity of sonographically guided CNB for the diagnosis of breast cancer was 96.3%. CONCLUSIONS: Sonographically guided 14-gauge CNB is a safe and accurate method for evaluating breast lesions that require tissue sampling. Radiologic-pathologic correlation and follow-up of benign lesions are essential for a successful breast biopsy program.  相似文献

OBJECTIVE: To determine whether sonography can be used to categorize some solid breast masses as probably benign so that biopsy can be deferred. METHODS: We prospectively characterized 844 sonographically visible solid breast masses referred for biopsy. Mammographic and sonographic features of the masses were recorded, and all masses were categorized by American College of Radiology Breast Imaging Reporting and Data System classification before biopsy. Of the 844 masses, 148 were categorized as probably benign (Breast Imaging Reporting and Data System category 3). Sonographically guided biopsy (n = 804) or fine-needle aspiration (n = 40) was performed for pathologic correlation. RESULTS: Of the 148 masses that met the sonographic criteria for probably benign masses, there was 1 malignancy, for a negative predictive value of 99.3%. CONCLUSIONS: Follow-up can be an acceptable alternative to biopsy for sonographically probably benign solid masses.  相似文献

OBJECTIVE: The purpose of this presentation is to illustrate the sonographic findings of chest wall lesions that were depicted on breast sonography. METHODS: Chest wall lesions detected during breast sonography were collected and reviewed retrospectively. RESULTS: The sonographic findings of normal chest walls and various pathologic chest wall lesions, including inflammatory lesions, benign neoplasms, and malignant neoplasms, are discussed. CONCLUSIONS: Familiarity with normal sonographic anatomy and chest wall lesions could be helpful in differentiating a chest wall lesion from a breast lesion and in showing whether the origin of any palpable breast lump is in the breast parenchyma or the chest wall on breast sonography.  相似文献

OBJECTIVE: Large-core needle biopsy of the breast can be performed with stereotactic or ultrasonographic guidance. However, ultrasonographically guided large-core needle biopsy has notable advantages, including the absence of ionizing radiation, increased patient comfort, and greater cost-effectiveness. The purpose of this study was to evaluate the accuracy of ultrasonographically guided large-core needle biopsy for the diagnosis of breast cancer in palpable and nonpalpable breast masses. METHODS: The study was a retrospective review of consecutive ultrasonographically guided large-core needle biopsies for indeterminate breast masses. A total 424 ultrasonographically guided core biopsies were performed in 367 patients with 1 or more breast masses. Ultrasonographically guided core biopsy was performed with a 14-gauge spring-loaded needle and a freehand technique. Correlation of ultrasonographically guided core biopsy pathologic findings with subsequent surgical pathologic findings or long-term imaging follow-up was performed. RESULTS: Of 424 indeterminate breast lesions for which histopathologic findings were obtained by ultrasonographically guided core biopsy, 234 cancers were diagnosed. Twenty-eight additional lesions had either questionable but not definitively malignant pathologic features (n = 11) or radiologic-pathologic discordance (n = 17) and were surgically excised. Of these, 8 additional cancers were diagnosed. Patients or surgeons chose excision of 41 additional lesions that were benign on ultrasonographically guided core biopsy No cancer was found in these surgical specimens. One additional cancer was diagnosed at a 6-month imaging follow-up because of interval growth. On the basis of surgical and long-term imaging follow-up, the sensitivity of ultrasonographically guided core biopsy for the diagnosis of breast carcinoma was 99.2% (95% confidence interval, 95.6%-99.9%) in 173 palpable breast masses and 93.2% (95% confidence interval, 87.1%-97%) in 251 nonpalpable masses. In cancers diagnosed on the basis of immediate surgical excision as a result of ultrasonographically guided core biopsy that showed either questionable pathologic features or radiologic-pathologic discordance, the sensitivity of ultrasonographically guided core biopsy for the diagnosis of breast cancer was 99.2%. CONCLUSIONS: Ultrasonographically guided large-core needle biopsy is a sensitive percutaneous biopsy method for the diagnosis of breast cancer in palpable and nonpalpable breast masses.  相似文献

OBJECTIVE: To evaluate the role of combined mammographic and sonographic imaging in patients with palpable abnormalities of the breast. METHODS: Four hundred eleven consecutive cases of palpable abnormalities of the breast underwent combined mammographic and sonographic evaluation. Patients who did not undergo biopsy had imaging and clinical follow-up; the mean follow-up period was 28.9 months (range, 24-33 months). RESULTS: One hundred sixty-five (40.1%) of 411 palpable abnormalities had a benign assessment; 97 (58.7%) of the 165 benign lesions were visible on both mammography and sonography; 66 (40%) of 165 benign lesions were mammographically occult and identified at sonographic evaluation. In 60 (14.6%) of the 411 cases, imaging evaluation resulted in a suspicious assessment; 49 (81.7%) of the 60 lesions categorized as suspicious underwent biopsy; 14 (28.5%) of 49 lesions were histologically proved to be carcinoma. Nineteen (31.6%) of the 60 lesions categorized as suspicious were mammographically occult and identified only on sonography; 14 (73.7%) of these 19 lesions underwent biopsy; 12 (63.1%) of 19 were benign, and 2 (10.5%) were malignant. One hundred eighty-six (45.2%) of the 411 palpable abnormalities had negative imaging assessment findings; 12 patients with negative imaging findings underwent biopsy, and all had benign findings. The sensitivity (14 of 14) and negative predictive value (186 of 186) for a combined mammographic and sonographic assessment were 100%; the specificity was 80.1% (186 of 232). CONCLUSIONS: Cancer was diagnosed in 14 (3.4%) of 411 women who underwent combined imaging for palpable abnormalities of the breast. Combined mammographic and sonographic assessment was shown to be very helpful in identifying benign as well as malignant lesions causing palpable abnormalities of the breast.  相似文献

Hemangiomas are benign vascular tumors that are rare in the breast. A high percentage of hemangiomas are diagnosed incidentally during imaging examinations. They have mammographic, sonographic, and pathologic characteristics that allow radiologists and pathologists to diagnose them. We present four different cases of breast hemangiomas showing their mammographic and sonographic features. Two were diagnosed with an 18‐gauge core needle biopsy and they underwent surgical excision. The other two cases were diagnosed with a 14‐gauge core needle biopsy and their radiologic and pathologic appearances were concordant with breast hemangiomas, so they did not need surgical excision and are being followed. © 2012 Wiley Periodicals, Inc.

Excisional biopsy is the standard method of distinguishing benign from malignant masses of the breast. However, alternative, less invasive methods of diagnosis are needed to reduce the number of unnecessary biopsies, allay anxiety of the patient, and control costs. In this study, we evaluated breast masses in a series of patients using color Doppler sonography and gray scale ultrasonographic features. In all cases, the pathologic diagnosis of the breast mass was subsequently established by excisional biopsy. The accuracy of gray scale sonography exceeded that of color Doppler sonography at a significance level of P < 0.005.  相似文献

Accessory breast tissue results from failed regression of primitive mammary tissue and is most often located in the axilla. Accessory breast tissue itself is normal and should not be misdiagnosed as an abnormality. Both benign and malignant diseases that occur in the normal breast can also develop in accessory breast tissue in the axilla. In this pictorial essay, we show sonographic findings of normal accessory breast tissue in the axilla and various lesions that occur in accessory axillary breast tissue, along with other imaging findings and pathologic features.  相似文献

OBJECTIVE: To show a variety of benign breast lesions that exhibit posterior acoustic shadowing on sonography. METHODS: The cases illustrate a variety of pathologic breast conditions that were collected at a referral breast center at a tertiary medical center. RESULTS: A variety of pathologic conditions are discussed, with pathologic-imaging correlation. CONCLUSIONS: Although posterior acoustic shadowing is a sonographic feature that is most commonly associated with mammary malignancies, this sonographic finding may also be seen with benign breast lesions.  相似文献

Fine needle aspiration biopsy is a widely used technique for the initial diagnosis of mammary lesions. The majority of patients undergoing fine needle aspiration biopsy of a breast lesion will have a benign disease of the breast. This article provides a review of the cytomorphologic features in a variety of benign breast lesions,and discusses the commonly encountered differential diagnoses on aspiration biopsy. Topics discussed include inflammatory and reactive conditions, treatment-induced changes, pregnancy-related changes, benign proliferative lesions, and benign neoplasms of the breast.  相似文献

OBJECTIVE: The growing awareness of female breast cancer has led to increased sensitivity toward pathologic breast conditions in children and adolescents. Thus, approximately 15% of patients in child and adolescent gynecology are referred for the first time because of conspicuous features of the breast such as pain, palpable masses, and other findings on visual inspection. The aim of this study was to analyze the underlying diagnoses and diseases and determine the status of breast sonography in the diagnostic process. METHODS: The study population consisted of 62 female patients between 8 weeks and 20 years of age (1997-2002) who were examined clinically, followed by standardized sonography (7.5-13 MHz, conventional B-mode panoramic sonography). Presumed diagnoses were confirmed by biopsy in some patients (n = 16) and by follow-up with clinical examination and sonography in most cases (n = 46). RESULTS: The clinical and sonographic evaluation confirmed 4 main groups of diagnoses: benign tumors (15), developmental disturbances (14), cystic changes (11), and inherent defects (7). In the remaining cases, the findings were no abnormality (9), nipple discharge without evidence of pathologic or morphologic correlates (3), abscesses (2), and epidermoid cyst (1). CONCLUSIONS: Knowledge of regular breast development and its variants is essential for the physician. Given knowledge of the sonographic appearance of physiologic breast development and specific lesions, breast sonography is most helpful in identifying and characterizing abnormalities and guiding further investigation.  相似文献
