The celiac “seagull” (Fig. 1) refers to the division of the celiac trunk into the hepatic artery and splenic artery, which resembles a seagull soaring (Fig. 2).

Anatomically, the celiac artery arises from the abdominal aorta from level of the twelfth thoracic vertebra and trifurcates into the common hepatic, splenic artery, and the left gastric artery.

The “seagull” is observed in a transverse plane over the epigastrium, and serves as a useful landmark for identification of the celiac trunk [1].
