[Homonymous lateral hemianopsia as a presenting sign of intracranial extracerebral cavernous hemangioma].

A case of intracranial extracerebral cavernous hemangioma of the middle fossa in a woman who suffered from a multiple sclerosis, is reported. Appearance of a lateral hemianopia suggested an other disease than multiple sclerosis to explain this symptom. Intracranial extracerebral cavernous hemangioma is a rare tumor reported more often in the middle fossa than in other sites. It usually produces symptoms by compression of nearby structure. Diagnosis is based on neuroradiological examination and we describe the MRI aspect. It is difficult to remove because of massive hemorrhage.
