良性转移性平滑肌瘤的病理特点及CT表现分析

Metastatic benign leiomyoma pathology and CT performance analysis

目的 :探讨转移性平滑肌瘤组织学与生物学的病理特点及其CT表现。方法 :回顾性分析32例转移性平滑肌瘤的患者,重点分析其病理特点及CT表现。结果 :32例均为女性,平均年龄44.5岁,均有子宫肌瘤病史,23例为肺转移,主要症状为咳嗽;腹膜后转移1例;肝脏转移1例;脊柱椎体转移1例,盆腔内腹膜播散型6例。所有病灶CT均表现为边界清晰的良性结节或肿块。结论 :在有子宫肌瘤病史女性中,CT中见到边缘光滑、清楚、密度均匀的结节或肿块时要考虑到BML的可能,熟悉其组织学良性而生物学恶性的病理特点,对疾病的治疗及预后有重要临床意义。

Objective To investigate the histological features and CT manifestations of metastatic leiomyoma.Methods 32 patients with metastatic leiomyoma were analyzed retrospectively,and their pathological features and CT findings were analyzed.Results All the 32 cases were female,with an average age of 44.5 years,with a history of uterine fibroids,23 cases of lung metastasis,and the main symptoms were cough.1 case of retroperitoneal metastasis;1 case of liver metastasis;1 case of vertebral body metastasis,6 cases of peritoneal disseminated in pelvic cavity.All lesions showed benign nodules or masses with clear boundary.Conclusion In the history of uterine fibroids in women,in the CT,edge smooth,clear,uniform density should consider when nodules or masses BML may,familiar with the histological pathological characteristics of benign and malignant biology,treatment and prognosis of disease has important clinical significance.
