【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。 更多还原
【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 fr... 更多还原 【关键词】 孤立性纤维瘤; 颅内肿瘤; 体层摄影术,X线计算机; 磁共振成像; 【Key words】 Solitary fibrous tumor Intracranial tumor Tomography; X-ray Computed Magnetic resonance imaging; 【分类号】R743.3
