孤立性纤维性肿瘤 MSCT 表现

目的：探讨孤立性纤维性肿瘤（ SFT）的多层螺旋CT（ MSCT）表现。方法：收集我院经手术病理证实的9例孤立性纤维性肿瘤患者的临床资料，对其MSCT表现进行回顾性分析。结果：9例孤立性纤维性肿瘤中，位于胸部6例，腹腔2例，盆腔1例。 MSCT检查见：较小病灶边缘规则，较大病灶呈分叶样；6例边界清晰，3例边界不清；7例密度较均匀，2例见不规则坏死区，1例见点状钙化；增强扫描动脉期呈轻到中度强化，静脉期持续性强化。结论：SFT的MSCT表现具有一定特征性，正确认识其MSCT的影像学特点，可有助于提高该病术前诊断的准确率。

MSCT Manifestations of Solitary Fibrous Tumours

Objective：To investigate the MSCT manifestations of solitary fibrous tumours （ SFT ） . Methods：The MSCT manifestations of 9 patients with pathologically proved SFT were analyzed retrospectively . Results：6 of 9 cases with SFT were located in the chest , 2 cases in the abdomen and 1 case in the pelvis . Small tumors were smooth contours , larger tumors were characterized by lobulated contours .6 cases had well-defined contours , and 3 cases had ill-defined contours .7 cases were homogeneous density .2 cases showed ir-regular necrosis.Calcification was seen in 1 case.The tumors were mild to moderate enhanced after contrast -enhanced scans ,and continous enhancement in the venous phase .Conclusions：The MSCT manifestations of SFT have characteristic , we can boost the accurate rate of preoperative diagnosis with SFT by correctly grasping its imaging characteristic .
