Pathology and MR Features of Intracranial Cavernous Hemangioma

Objective:To analyze the MR findings of intracranial cavernous hemangioma combined with pathologic features.Methods:53 cases of intracranial cavernous hemangioma were collected and studied.Among them,40 cases were intracerebral cavernous hemangiomas and 13 cases were extracerebral cavernous hemangioma.All the cases were examined by MRI.Results:Intracerebral cavernous hemangiomas generally showed popcorn-and mulberry-like mixed signals with ring-like low signal on MRI;Extracerebral cavernous hemangiomas showed homogenous low signal on T1WI and high intense signal on T2WI.After injecting contrast medium,the tumor signals were enhanced markedly.Conclusion:The different types intracranial cavernous hemangiomas have different pathologic features that result in different MR findings,leading to different operation plans and prognosis.As a result,the intracranial cavernous hemangioma can be diagnosed correctly by MR before operation which guides the operation plan.
