目的探讨乳腺错构瘤的X线表现与病理基础。方法收集经手术病理证实的乳腺错构瘤19例,分析其X线表现与病理学基础,全部病例均采用全数字化乳腺X线摄影。结果X线表现脂肪型5例,致密型4例,混合型10例。病理上本病均有完整的包膜,由数量不等、杂乱无章的乳腺导管、小叶和成熟的脂肪及纤维组织混杂组成。结论乳腺错构瘤的X线表现因其病灶内脂肪组织、腺体和纤维组织的比例不同而不同,混杂密度肿块为本病的特征性X线表现。
Objective To investigate the X-ray findings and pathological basis of breast hamartoma. Methods Nineteen cases of breast hamartoma confirmed by surgery and pathology were collected and analyzed for their X-ray findings and pathology. All cases were fully mammographic. Results X-ray showed fat in 5 cases, dense in 4 cases and mixed in 10 cases. Pathology of the disease have a complete capsule, ranging from the number of chaotic breast duct, lobular and mature fat and fibrous tissue composition.
