Myxomatosic aneurysm of a brachial artery in a child.

We present a case of an aneurysm in a brachial artery of a 4.5-year-old child which was resected with the interposition of a venous graft. Histological examination of the aneurysm showed a myxomatous damage to the wall of the vessel. Examination of the cardiovascular system did not reveal a myxoma of the heart. The available literature was searched for a similar description of an isolated aneurysm of a peripheral artery but none was found.
