We present a case of subarachnoid and intraventricular hemorrhage due to an infratentorial metastasis of a renal cell carcinoma. The lesion was not apparent on initial magnetic resonance imaging (MRI) or in a follow-up examination (MRI and angiography) 6 weeks after the bleeding. The innocent bilateral posterior communicating artery aneurysms detected by cerebral angiography were treated surgically. The origin of the hemorrhage, however, remained unclear. Five months later, a surgically proven metastasis in the fourth ventricle subsequently gave the explanation for the bleeding.
我们报告一例因肾细胞癌幕下转移导致蛛网膜下腔和脑室内出血的病例。在最初的磁共振成像（MRI）检查中以及出血后6周的随访检查（MRI和血管造影）中，病变均不明显。脑血管造影检测到的双侧无症状后交通动脉瘤接受了手术治疗。然而，出血的来源仍不清楚。五个月后，手术证实的第四脑室转移瘤为出血原因提供了解释。
