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.
海绵状血管畸形（CMs）以含铁血黄素环和病灶内出血为特征，是相对常见的颅内血管畸形。CMs引起的病灶外出血在少数病例中可见，但大多数在磁共振成像上显示典型的CM表现。在此，作者报告两例经病理证实的CM，表现为不寻常的大脑内大出血，且未被典型的含铁血黄素环所包围。在鉴别诊断大量大脑内出血时，应考虑表现为大脑内大出血的CMs。
