Intracranial Cavernous Hemangioma:CT and MRI Diagnosis

Objective:To investigate the imaging features and value of CT and diagnostic MRI in the diagnosis of intra- and extracerebral cavernous hemangioma.Mathods:CT and MRI data of 45 cases of intracerebral and extracerebral cavernous hemangioma were studied retrospectively.45 cases were performed MRI,and 30 cases of CT.There were 42 cases of intracerebral cavernous hemangioma and 3 extracerebral cavernous hemangiomas,all cases were confirmed pathologicaly.Results:The lesions of intracerebral cavernous hemangioma could be located in any position of the brain,single lesion was more commom.Most lesions had no or slightly edema without mass effect.CT features of 27 cases included:slightly higher or mixed density mass without contrast enhancement.MRI features on T2WI were mulberry-like inhomogenous high signal intensity with flocculent hypointensity ring.Only few lesions were slightly enhancement.Extracerebral cavernous hemangioma were located in the middle fossa and parasellae,dumbbell shape,and homogenous slight hypointensity on T1WI and hyperintensity on T2WI images with markedly enhancement.Conclusion:The CT and MRI findings of intracerebral and extracerebral cavernous hemangioma are specific,MRI is superior to CT,especially the T2WI image is important significance for diagnosis.
