Abstract
We report a case of a subacute expanding intracerebral hematoma associated with a cavernous angioma. A 68-year-old man was presented with transient unconsciousness. He had a past history of mild thrombocytopenia, which was suspected to be ITP (idiopathic thrombocytopenic purpura). Computed tomography (CT) showed right frontal subcortical hemorrhage (2 cm). Repeated CT revealed a gradual enlargement of the hematoma with an eccentric high intensity area. The hematoma had grown up to 6 cm in diameter when the patient showed disorientation. On the 17th day from the onset, the operation was performed and a liquefied intracerebral hematoma with no capsule and a hemorrhagic mural mass were removed. The pathological finding of the mass was a cavernous angioma. It is a rare case that a continuous enlargement of the hematoma after the initial bleeding from the cavernous angioma was followed by CT scan. In this case, mild thrombocytopenia might be one of the causes of the initial overt hemorrhage and the following enlargement of the hematoma.
