Objective To investigate the diagnosis and the causes of misdiagnosis of skull base chondrosarcoma.Methods The clinical data of 7 cases of skull base chondrosarcoma confirmed by pathology from April 2009 to February 2014 were analyzed retrospectively.Results Only 1 case of preoperative diagnosis was correct in 7 cases of skull base chondrosarcoma, other 6 cases were misdiagnosed, of which 2 cases were misdiagnosed as trigeminal schwannoma, 3 cases were misdiagnosed as chordoma, 1 case was misdiagnosed as meningioma,the misdiagnosis rate was 85.7％.Conclusion Chondrosarcoma of the skull base is rare, so clinicians are lack of knowledge, and non-characteristic clinical features and non-characteristic radiographic manifestations contribute to misdiagnosis.Strip calcification on CT and honeycomb reinforced on enhanced MRI existing at the same time,which prompts to diagnosis chondrosarcoma of the skull base.
