腹盆部孤立性纤维性肿瘤的影像学表现与临床病理分析

目的 探讨发生于腹盆部的孤立性纤维性肿瘤（solitary fibrous tumor,SFr）的影像学表现.方法 回顾性分析11例发生于腹盆部的SFT患者的影像学表现及临床、病理特征.结果 11例SFT患者中,位于腹部者2例,盆腔者9例.影像学主要表现为边界清晰,较明显强化的软组织肿物,其中5例伴有囊变/黏液样改变,3例伴钙化.仅1例MR见典型纤维组织信号.结论 发生于腹盆部的SFr虽然在影像学表现上具有一些特征,但CT、超声和MR三种检查方法对SFT的检查应以发现及定位病变为主,正确的诊断应建立在充分了解SRT的影像学表现及其鉴别诊断的基础上.

Imaging features and clinicophathological manifestation of solitary fibrous tumors originated from abdomen and pelvis

Objective To investigate the imaging characteristics of solitary fibrous tumors （SFT） originated from ab- domen and pelvis. Method The imaging findings and clinicophathological manifestations of 11 patients with SFT origina- ted from abdomen and pelvis were analyzed retrospectively. Result SFT were in abdomen in 2 cases, and in pelvis in the other 9 cases. Imaging examinations showed that most of the SFT were well-defined soft tissue masses with intense enhance- ment. 5 cases exhibited cystic/myxomatoid changes, and calcifications were seen in 3 cases. Only 1 case showed typical manifestations of fibrous tissue on MR scan. Conclusion Although imaging characterizes SFTs originated from abdomen and pelvis, the primary application of the examinations at present is to detect and locate the lesions, and further proper di- agnosis relies on sufficient comprehension of the imaging characteristics and the differential diagnosis.
