Renal fibromuscular hyperplasia associated with subarachnoid hemorrhage from a berry aneurysm: a case report.

An 11-year-old girl with renal artery fibromuscular hyperplasia and a berry aneurysm of the anterior communicating artery with subarachnoid haemorrhage is reported. She presented with subarachnoid hemorrhage and was shown to have hypertension attributable to unilateral renal artery fibromuscular hyperplasia. Cerebral angiography showed an aneurysm of the anterior communicating artery. The aneurysm was not treated surgically, but control of the hypertension was obtained by renal revascularisation with an aortorenal graft of saphenous vein. The patient remained well subsequently, and follow-up angiography demonstrated virtual disappearance of the aneurysm and also a functioning aortorenal graft.
