We report three cases of ruptured cerebral aneurysms associated with systemic lupus erythematosus (SLE). A 52-year-old woman (case 1) with a fifteen-year history of systemic lupus erythematosus suddenly lost consciousness. She was admitted in a state of deep coma. A computed tomography (CT) scan revealed acute hydrocephalus and diffuse subarachnoid hemorrhage in the basal, interhemispheric and bilateral Sylvian cisterns. Fifteen years prior to this admission, cerebral angiograms demonstrated no cerebral aneurysm. She underwent ventricular drainage immediately. Postoperatively, her condition did not improve, and she died on the 18th day. During the autopsy, two saccular cerebral aneurysms were found: one aneurysm was at the right middle cerebral artery bifurcation, and another one was on the anterior communicating artery, which had disruption of the internal elastic lamina and medial smooth muscle, and infiltration of inflammatory cells. In the major cerebral arteries, for example the bilateral internal carotid arteries, disruption or dissection of the internal elastic lamina, intimal fibrosis and transmural infiltration of inflammatory cells were observed. The second patient, a 36-year-old woman with a six-year history of SLE, was admitted to our hospital with sudden severe headache. A CT scan showed subarachnoid hemorrhage, and cerebral angiograms disclosed saccular cerebral aneurysms on the anterior communicating artery and the left superior cerebellar artery, and a fusiform one on the left posterior cerebral artery. Surgery was not recommended because of her multiple medical problems. Her consciousness improved gradually over 2 months. She was transferred to the department of internal medicine for treatment of renal failure.(ABSTRACT TRUNCATED AT 250 WORDS).
