Persistent primitive trigeminal artery, cavum septi pellucidi, and associated cerebral aneurysm in a patient with polycystic kidney disease: case report.
A 51-year-old man with polycystic kidney disease had a persistent primitive trigeminal artery, cavum septi pellucidi, and an unruptured cerebral aneurysm. He had a history of long-standing hypertension, but not of subarachnoid hemorrhage. Computed tomograms revealed cavum septi pellucidi. Because of the polycystic kidney disease, we performed four-vessel cerebral angiography, which revealed a persistent primitive trigeminal artery and a cerebral aneurysm at the bifurcation of the left internal carotid artery. The neck of the aneurysm was clipped successfully without producing any neurological deficit. The clinical significance of the combination of these multiple anomalies and cerebral aneurysms is discussed.
