Objective：To discuss on CT and MRI imaging features and treatment of cavernous hemangioma in cavernous sinus（CHCS） and to promote the diagnostic and treatment level. Methods：Totally 13 patients with surgically and pathologically verified CHCS were reviewed. All cases were examined by CT and MRI plain scan and contrast-enhanced scan． Results：Lesions located at the left side in seven cases and at the right side in six cases with the length of 3.5-6.8 cm（4.6 cm in average）. Eleven cases were ‘dumbbell-shaped’ or ‘gourd-like’ and 2 cases were in round shape. Ipsilateral internal carotid artery of 13 cases were wrapped or extruded and middle cerebral artery of five cases were pressed，without showing obvious lumen narrow，exact feeding arteries and draining veins. There was no edema around and four cases were in association with the sphenoid mild bone absorption erosion. CT scan of 12 cases showed evenly or slightly higher density，CT scan of one case showed hemorrhage and unevenly high density and no calcification and cystic degen－eration was observed. On T1WI of MRI scan，six cases exhibited cerebral gray matter signal，six cases exhibited slightly below cerebral gray matter signal and one case showed heterogeneous high signal. T2WI showed evenly high signal similar to cerebrospinal fluid in 12 cases and one case exhibited mixed-signal. Enhanced CT scan showed that five cases were evenly moderately enhanced and eight cases were significantly strengthened. Enhanced MRI of 13 patients showed that all patients were significantly strengthened and 6 cas－es were evenly enhanced at early stage and unevenly enhanced at late stage with more significant degree and similar delay filling en－hancement patterns. On DWI maps，nine cases showed equal signal，two cases with slightly higher signal，one case with mixed-signal and one case with slightly lower signal. Apparent diffusion coefficient（ADC） maps showed a significantly higher signal and ADC val－ue was （1.56±0.37）×10-3 mm2/s. Conclusions：CT and MRI findings of CHCS have some characteristic and are helpful for preoper－ative diagnosis. CT and MRI examination can show accurately the anatomical relationship of lesions，blood vessels and nerves and have important guiding value for clinical treatment.
