A 50-year-old woman was admitted to our hospital to undergo surgery to remove a pituitary adenoma. Preoperative dynamic computed tomography revealed an incidental right gastroepiploic arterial aneurysm (GEAA). After removal of the pituitary adenoma, we performed a laparoscopic right gastroepiploic aneurysmectomy. The postoperative course was uneventful. Right GEAAs should be treated at diagnosis owing to the high possibility of rupture. Laparoscopic right gastroepiploic aneurysmectomy is feasible and should be considered for the treatment of right GEAAs.
