title: Two cases of cavernous malformation presenting with unusual and large intracerebral hemorrhages.
abstract: Cavernous malformations (CMs), characterized by the presence of a hemosiderin rim and intralesional hemorrhage, are relatively common intracranial vascular malformations. Extralesional hemorrhages arising from CMs are seen in a minority of cases, but most of them show typical CM findings on magnetic resonance imaging. Here, the authors report two cases of pathologically confirmed CM presenting with unusual and large intracerebral hemorrhages, which were not surrounded by the typical hemosiderin rim. CMs presenting with large intracerebral hemorrhage should be considered in the differential diagnosis of massive intracerebral hemorrhages.
