Objective To evaluate the perfusion weighted imaging (PWI) and magnetic resonance spectroscopy (MRS) cavernous hemangioma around the saddle and saddle beside the differential diagnosis of meningioma. Methods A retrospective analysis of six confirmed cases in the cavernous hemangioma and 10 cases in the patients with meningiomas mri routine scan, MRS, PWI and enhanced scan image data, measurement of tumour biggest region blood volume (rCBV) value and normal white matter area of region blood volume and ratio of the two (nCBV), statistical analysis was carried out on the nCBV values between the two groups. Results The results of conventional and enhanced scan in both difficult to identify, but the nCBV value of the meningioma near the saddle (6.119±2.564) was significantly higher than those in the cavernous hemangioma group (1.367±1.132). In the cavernous hemangioma spectrum characteristics to N-acetyl aspartate , choline and creatine peak, see clear lipid peak. Next to the saddle meningioma no N-acetyl aspartate, creatine, such as peak, 3 cases of visible peak alanine, see clear choline peak, both MRS has obvious differences in performance. Conclusion MRS joint PWI beside the saddle in the cavernous hemangioma and has high value in the differential diagnosis of meningioma.
