[Allergic granulomatous angiitis with subarachnoid hemorrhage--a case report].
A case of allergic granulomatous angiitis showing various symptoms of the central nervous system is reported. A 29-year-old female was admitted to our hospital because of severe headache and urinary incontinence. Consciousness was drowsy, and right IIIrd cranial nerve palsy was observed. CT scan revealed subarachnoid hemorrhage, hydrocephalus and arachnoid cyst. Since no aneurysm or arteriovenous malformation was detected by angiography, continuous ventricular drainage was performed. Marked hypertension due to renal vascular origin was suggested by means of laboratory data about serum renin etc., so renal as well as cerebral angiography was carried out by Seldinger's method. There revealed aneurysms of the left renal artery and a branch of the left anterior cerebral artery. Then, ventriculo-peritoneal shunt and resection of left frontal aneurysm were done. Microscopic finding of the excised aneurysm was necrotizing angiitis with infiltration of eosinophil. Six days after the operation, CT scan showed asymptomatic subcortical hematoma at the right occipital lobe. The patient was in good condition and had no cerebral or other complication following steroid therapy. The present case was considered as a very rare one because no case with subarachnoid hemorrhage and cerebral aneurysm due to allergic granulomatous angiitis was reported in the previous literature.
