A Case Series of Malign Hyperechoic Breast Lesions

Background: Hyperechoic breast lesions are a rare group of breast masses in routine practice. Most of these lesions are benign. However, they rarely may be malignant. Hyperechoic lesions can be evaluated using the same criteria for malignant lesions. Clinical history, mammo-graphic appearance, and certain sonographic features (non-circumscribed margins, irregular shape, presence of hypoechoic areas, nonparallel orientation, and association with microcalcifications can be suggestive of malignancy). In this article, hyperechoic breast lesions with malignant pathology have been presented. Methods: Seven cases during breast ultrasound examination were detected. Results: Four patients had invasive ductal carcinoma, 1 patient had invasive lobular carcinoma, 1 patient had high-grade ductal carcinoma in situ (DCIS), and 1 patient had lymphoma. Ultrasonography of the breast showed a heterogeneous appearance in all the patients, microcalcification in two patients, and an ambiguous contour in one patient. Conclusion: Hyperechoic breast lesions should be evaluated using specific sonographic criteria to prevent misdiagnosis and identify patients who require biopsy and further examination.
