| 摘 要： | 目的分析颅内孤立性纤维瘤的CT和MRI表现,提高对其认识。资料与方法回顾性分析5例经手术病理证实的颅内孤立性纤维瘤的CT和MRI表现。1例行CT增强扫描,3例行MRI平扫和增强扫描,1例同时行CT和MRI扫描。结果 5例颅内孤立性纤维瘤均为单发,肿块形态不规则,边界清楚,直径1.2～6.5 cm。发生于颞叶1例,鞍内1例,桥小脑角区1例,中后颅窝三叉神经走行区1例,顶叶1例。CT平扫病灶均为高密度,增强扫描均匀强化。MR T1WI上3例病灶为等信号;1例为多发分隔囊状低信号。T2WI上3例病灶表现为等、低混杂信号,病灶内见少量斑片状高信号;1例为多发分隔囊状高信号。MRI增强所有病灶实质部分显著强化,T2WI低信号区明显强化,坏死囊变区未见强化。结论颅内孤立性纤维瘤MRI表现有一定的特点,MR T2WI上低信号、增强扫描呈显著强化较具特征。

| Abstract: | Objective To study the CT and MRI features of intracranial solitary fibrous tumor(ISFT) and improve the understanding of ISFT.Materials and Methods CT and MRI findings were retrospectively reviewed in 5 patients with ISFT proved by operation and pathology.CT enhanced scan was performed in one patient;plain and enhanced MRI scan were performed in three patients,both CT and MRI scans were examinated in one case.Results All of the tumors were found as a solitary,well-defined mass,ranging in size from 12 to 65 ... |
