Abstract:
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.
