Cerebral aneurysm in an infant with fibromuscular hyperplasia of the renal arteries. Case report.
The authors report a case of subarachnoid hemorrhage in an 11-month-old infant with tragic outcome. Radiological investigation showed an anterior communicating aneurysm, and postmortem examination confirmed the aneurysm to be a so-called "berry" aneurysm. There were also typical signs of fibromuscular hyperplasia of the renal arteries. The microscopic findings are discussed. In view of the rarity of both aneurysms and fibromuscular hyperplasia in such a small child, a possible association of these entities suggested by several earlier investigators is reviewed.
