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 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.

Case Reports
Computerized tomography (CT) localized stereotactic craniotomy for excision of a bacterial intracranial aneurysm.
The treatment of bacterial intracranial aneurysms include long-term antibiotic therapy and surgical clipping or resection. Direct surgical approaches to these aneurysms are often complicated by their peripheral location. ⋯ In the future, stereotactic craniotomy may facilitate aggressive surgical therapy for infectious aneurysms previously thought not suitable for direct operative approach.
