Subarachnoid and intraventricular hemorrhage caused by hypernephroma metastasis, accompanied by innocent bilateral posterior communicating artery aneurysms

Surg Neurol. 1995 Sep;44(3):275-8. doi: 10.1016/0090-3019(95)00170-0.


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.
