To summarize the magnetic resonance imaging(MRI)features and microsurgical treatment of cavernous sinus hemangiomas(CSH). Twenty-three patients with surgically and pathologically verified CSH were reviewed. All patients underwent computed tomography(CT)and MR scan, 19 cases underwent MR diffusion-weighted imaging(DWI)and 7 underwent single voxel (1)H magnetic resonance spectroscopy((1)HMRS)before operation. The microsurgery through modified pterional approach was performed in 11 cases and 12 cases removal was achieved in combined fronto-temporal preauricular subtemporal approach. Nineteen cases with large tumors were treated by Leksell Gamma knife(LGK)before operation. CSHs were single, large, and spherical/lie gourd-shaped tumors across the inside and outside the sella. CSH showed equal or slightly low signal on T1WI, high signal on T2WI and FLAIR, homogeneous or heterogeneous great enhancement on MR enhancement scan 19 cases showed equal or slightly low signal on DWI, 7 cases showed no NAA, Cr, and Cho peak
