The Diagnosis Value of CT MRI and DSA in Intraaxial Cavernous Hemangioma

Objective To discuss the value of CT,MRI and DSA in the diagnosis of intracranial cavernous hemangioma. Materials and Methods Twenty-two patients with intracranial cavernous hemangioma confirmed by operation were retrospectively analyzed. All the patients performed CT and MR plain scan. 17 and 13 cases of them performed enhanced CT and enhanced MRI scan as well. 5 cases were checked with DSA. Results Intracranial cavernous hemangioma showed hyperdensity,slight hyperdensity or isodensity on CT images. Some lesions appeared isointensity or slight hypointensity on T1WI and hyperintensity on T2WI. Some lesions appeared hyperintensity on both T1WI and T2WI with hypointensity circle surrounded. The other cases appeared hypointensity on T1WI and T2WI. The lesions had no mass effect and enhancement. There was no tumor stain on DSA images. Conclusion The MRI is superior to CT in diagnosing intracranial cavernous hemangioma. It is an effective method to analyze the intracranial cavernous hemangioma combined with CT and DSA.
