A 42-year-old man noted a left hypothenar
mass about one week after hitting the palm of his left hand.
Although he did not seek treatment, numbness and cyanosis of
the left 2nd, 3rd, 4th, and 5th digits appeared suddenly about
one year later. A computed tomography scan revealed an ulnar
artery aneurysm with a mural thrombus, with a maximal diameter
of 20 mm, at the site where the ulnar artery passed near the
hamate bone. The aneurysm was excised, and the ulnar artery was
reconstructed with direct end-to-end anastomosis. Traumatic ulnar
artery aneurysm is commonly seen in workers who use the hypothenar
eminence of their hands as a hammer, and is usually accompanied
by finger ischemia.
