[Ruptured aneurysm at the peripheral branch of the posterior cerebral artery with systemic lupus erythematosus]

Abstract

We report a 73-year-old woman with systemic lupus erythematosus (SLE) in whom intracerebral and intraventricular hemorrhage developed secondary to a ruptured aneurysm on the peripheral branch of the posterior cerebral artery. We reviewed data on 22 patients (43 aneurysms) in previous reports of ruptured cerebral aneurysms associated with SLE, including our case. Of these aneurysms, 34 (79.1%) were located on the major artery, and 9 (20.9%) were located on the peripheral small artery. Fusiform aneurysms accounted for 27.9% of the total. The prognosis was poor, and 14 patients (63.6%) died. Direct aneurysmal surgery was performed in 11 patients (50%), but 4 patients died of other diseases associated with SLE.
