目的：回顾性分析9例经手术病理证实的颅内软骨瘤的CT、MRI征象,结合文献,探讨其影像学诊断。方法9例病例中,8例行头部CT扫描；4例行头部 MRI扫描,MRI扫描序列采用自旋回波 T1 WI、T2 WI、FLAIR、DWI 序列及 T1 WI 增强。结果8例病灶位于颅底,1例位于凸面硬膜。CT显示8例病灶内见点条状或边缘弧形钙化,MRI显示4例(4/4)病灶 T1 WI呈低等混杂信号,T2 WI呈高等混杂信号,2例(2/4)T2 WI 见多发结节样或分叶样高信号,2例(2/4)T2 WI 见珊瑚样分隔状等信号并且于T1 WI增强后见分隔明显强化,4例病灶包膜都明显强化。结论颅内软骨瘤有较明显的CT和MRI征象,MRI征象可以反映颅内软骨瘤的病理组织学特点。

Objective To analyse CT and MRI features of intracranial chondromas and review the literatures.9 cases of intracra-nial chondromas confirmed by operation and pathology were presented.Methods Among 9 cases,cerebral CT scan was performed in 8 cases(8/9),MRI scan in 4 cases(4/9)with spin-echo T1 WI,T2 WI,FLAIR,DWI sequences and enhanced T1 WI sequences.Results The lesions located at the skullbase in 8 cases,the dural convexity in 1 case.CT showed that the lesions were spot,strip or arc of fringe calcifications in 8 cases.MRI showed that the lesions were inhomogeneous low and moderate signal intensity on T1 WI and in-homogeneous high and moderate signal intensity on T2 WI in 4 cases(4/4).Multinodular or lobed high signal intensity was seen on T2 WI in 2 cases(2/4),coralline septal moderate signal intensity was seen on T2 WI ,which was obvious enhancement after adminis-tration of contrast medium on T1 WI in 2 cases(2/4),the envelope of the lesions was also obvious enhancement in 4 cases.Conclu-sion CT and MRI features of intracranial chondromas are marked.The MRI features of intracranial chondromas can reflect its path-ologic and histologic characteristics.
