摘　　要：目的探讨胸膜外孤立性纤维瘤的影像学表现。方法回顾性分析8例经手术病理证实的胸膜外孤立性纤维瘤的CT和MR表现。结果发生于颅内3例、腹部4例、四肢软组织1例。CT均呈密度均匀或不均匀的类圆形、分叶状较高密度的软组织块影,CT值约40.0Hu。MR表现为,T1低或等信号,T2高或低信号。增强后肿瘤实质区明显强化。结论胸膜外孤立性纤维瘤广泛分布,CT呈较高密度软组织影、病灶内T2低信号及较为显著的强化是其特征性表现。Objective To report Imaging Findings of extrapleural solitary fibrous tumor. Methods CT and MR findings in 8 patients winl pathologically proved extrapleural solitary fibrous tumor were analyzed retrospectively.Results The tumor was found in head in 3 cases, 4 cases in abdomen, 1 cases in soft tissues of extremities.CT showed similar round or lobulated soft masses. MR demonstrated hypo- or equal signal on T1WI, hyper- or low signal on T2WI. Marked enhancement of solid components in the solid parts was showed post-enhancement.Conclusion Extrapleural solitary fibrous tumors distribute widespread, low signal on T2WI and marked enhancement are the special features.
