Two mammographically detected myoepithelial lesions (one each in women aged 77 and 73 years) were diagnosed at large-core needle biopsy, with the results confirmed by means of surgical excision. The imaging features were nonspecific. A key clue to the diagnosis at histologic examination was the presence of a well-defined capsule around the lesion; hence, sampling of the margins of the lesion is essential. Radiologists should be familiar with myoepithelial lesions in the differential diagnosis of fairly smoothly marginated solid masses.
通过乳腺钼靶检查发现的两个肌上皮病变（分别见于77岁和73岁女性），在粗针穿刺活检时被诊断出来，结果通过手术切除得到证实。影像学特征不具有特异性。组织学检查诊断的一个关键线索是病变周围存在明确的包膜；因此，对病变边缘进行取样至关重要。放射科医生在鉴别边缘相当光滑的实性肿块时应熟悉肌上皮病变。
