Rare Presentation of an Ulnar Artery Aneurysm in a Six-Month-Old Baby: Case Discussion.

Ulnar artery aneurysm cases have been rarely reported in the literature previously. A number of these cases occur in the adult population and are mostly occupational associated. In children, however, this condition is much less. Only 10 cases in children have been reported in the literature to the best of our knowledge, and the minimum age was 1 year. The etiology is mainly post-traumatic. We present a case for discussion of an ulnar artery aneurysm in a 6-month-old baby with the habit of hitting his hand against a table and the floor.
