目的:分析乳腺分叶状肿瘤(PTB)的全数字化乳腺摄影(FFDM)表现,以提高对该病的认识。方法:回顾性分析经手术病理证实的25例PTB的FFDM表现及临床资料,并与病理学分级结果相对照。结果:(1)25例PTB患者中,病理学分级为良性、交界性、恶性的百分比依次为40%、16%、44%;(2)FFDM主要表现为分叶状肿块,占88%;肿块边缘呈部分光整部分模糊为主,占64%;肿块最长径多大于3 cm,占68%;肿块周围异常血管显示率为68%;肿块伴钙化的发生率为24%,以良性多见,多表现为粗大散在斑状钙化;(3)FFDM诊断与病理诊断符合率为68%。结论:FFDM表现对PTB的诊断具有一定的指导意义。
Objective: To analyze full digital mammography (FFDM) of breast lobular tumors (PTB) to improve the understanding of the disease. Methods: The clinical data of 25 cases of PTB confirmed by surgery and pathology were retrospectively analyzed and compared with the pathological grading results. Results: (1) Among 25 cases of PTB, the pathological grade was benign, the percentage of borderline and malignant was 40%, 16% and 44% respectively. (2) FFDM mainly showed lobulated mass, accounting for 88%. The margin of the tumor was partly obscured, accounting for 64%; the longest diameter of the tumor was more than 3 cm, accounting for 68%; the rate of abnormal blood vessel around the tumor was 68%; the rate of tumor with calcification was 24% More common, mostly manifested as coarse scattered patchy calcification; (3) FFDM diagnosis and pathological diagnosis in line with a rate of 68%. Conclusion: The performance of FFDM is of guiding significance for the diagnosis of PTB.
