摘要
目的:分析腹盆部孤立性纤维性肿瘤(SFT)的CT与MRI表现。方法:回顾性分析2009至2019年福建省立医院收治的16例经手术病理检查证实为腹部、盆腔SFT患者的影像学表现,其中CT检查12例、MRI检查4例。结果:CT平扫检查表现为等低密度,密度不均10例、密度均匀2例。MRI平扫检查表现为4例T1WI呈低信号为主,1例T1WI夹杂斑片状高信号出血;4例T2WI呈混杂信号,呈不均匀稍高信号为主,内散在夹杂条片、斑片状低信号。CT及MRI增强扫描主要表现为不均匀明显持续性强化、地图样强化,部分呈轻度渐进性均匀强化。动脉期12例肿瘤内见迂曲分枝状、蔓状明显强化血管影。病理检查结果显示良性SFT 11例、恶性SFT 5例。结论:发生在腹部、盆腔的SFT较少见,但其CT、MRI表现具有一定的特征性。
Objective:To determine the CT and MRI findings of abdominal and pelvic solitary fibrous tumors(SFTs).Methods:The imaging manifestations of 16 patients,who were diagnosed with abdominal and pelvic SFTs by surgical pathology in Fujian Provincial Hospital between 2009 and 2019,were retrospectively analyzed,including 12 cases of CT and 4 cases of MRI.Results:The CT plain scan showed equal low density,and there were 10 cases of uneven density and 2 cases of uniform density.The MRI plain scan showed 4 cases of low signal on T1 WI;1 of patchy high-signal hemorrhage on T1 WI;and 4 of mixed signal on T2 WI,which were mainly uneven slightly high signal scattered in the striped and patchy low signal.The CT and MRI enhanced scans were mainly manifested as uneven and significantly continuous enhancement,map-like enhancement,and some of them were mildly progressive and uniformly enhanced.In the arterial phase,tortuous branching and plexiform were found in 12 cases of tumor with obvious enhancement of vascular shadow.The pathological examination showed 11 cases of benign SFTs and 5 cases of malignant SFTs.Conclusion:Abdominal and pelvic SFTs are rare,but their CT and MRI findings show certain characteristics.
