目的:分析乳腺髓样癌的X线表现与病理分型,提高对该病的影像诊断水平。方法:回顾性分析经手术病理证实乳腺髓样癌23例,观察其X线特点,并与病理进行对照。结果:23个病灶中表现为不伴钙化的肿块18个(78.3%),伴钙化肿块5个(21.7%)。23个肿块形状以圆形和卵圆形最为多见,分别占43.5%(10/23),34.8%(8/23);边缘主要表现为浸润性和小分叶状,分别占47.8%(11/23)和30.4%(7/23);肿块表现为高密度占60.9%(14/23),等密度30.4%(7/23)。结论:乳腺髓样癌X线表现以圆形或卵圆形高密度肿块为主要特点,很少伴有钙化,与其病理基础密切相关;但是典型髓样癌和不典型髓样癌在X线上无法鉴别。
OBJECTIVE: To analyze the X-ray findings and pathological classification of medullary mammary carcinoma to improve the imaging diagnosis of the disease. Methods: A retrospective analysis of 23 cases of breast medullary carcinoma confirmed by surgery and pathology, X-ray features were observed and compared with the pathology. Results: Twenty-three of the 23 lesions showed no calcification (78.3%) with calcified lumps (21.7%). The shape of the tumor was the most common with round and oval, accounting for 43.5% (10/23) and 34.8% (8/23), respectively. The margins were mainly infiltrative and lobular, accounting for 47.8% 11/23) and 30.4% (7/23). The lumps showed high density of 60.9% (14/23) and equal density of 30.4% (7/23). CONCLUSION: X-ray findings of medullary carcinoma of the breast are characterized by round or oval high-density mass with few calcifications and are closely related to its pathological basis. However, typical medullary carcinoma and atypical medullary carcinoma on the X-ray Unrecognized.
