title: Aneurysm of an aberrant splenic artery: An extremely rare occurrence.
abstract: An aberrant splenic artery arising from the superior mesenteric artery, also known as the splenomesenteric trunk, is a rare anatomical variant seen in less than 1% of the population and is more common in females. Aneurysms of the splenic artery originating anomalously from the superior mesenteric artery are extremely rare; only 35 cases of aneurysm of an aberrant splenic artery have been described so far in the English medical literature. We report an extremely rare case of aneurysm of aberrant splenic artery in a 28-year-old man in whom the lesion was detected during routine abdominal scanning and confirmed on computed tomography angiography. Aneurysms of an anomalous splenic artery originating from the superior mesenteric artery are extremely rare; however, they are clinically important because possible rupture could be catastrophic. Exploring these variations is important especially if surgical intervention is contemplated. This could greatly affect the surgical planning and avoid injuries to major arteries and organs intraoperatively.
