Brachial artery aneurysm in an infant: case report and review of the literature.

A case is reported of a congenital aneurysm of the brachial artery in a 9-month-old boy. The lesion was excised and the artery reconstructed with an end-to-end anastomosis. Review of the English language literature showed that brachial artery aneurysms in children usually occur in association with arteritis, connective tissue disorder, or a syndrome of multiple aneurysms of unknown origin.
