The rare case of a symptomatic atherosclerotic aneurysm of the superior epigastric artery mimicking an acute cholecystitis.

True aneurysms of the epigastric artery are rare. We report a case of a 65-year-old female who was admitted for increasing upper abdominal pain. A leukocytosis, pyrexia, breathing stop on inspiration, and a palpable mass next to the right costal arch with severe local pain were suspicious for acute cholecystitis.
