Multidetector Computed Tomography Findings of Mesenteroaxial Gastric Volvulus Combined with Torsion of Wandering Spleen: A Case Report and Literature Review

Abstract

Gastric volvulus is defined as an abnormal degree of rotation of one part of the stomach around another (1). Gastric volvulus may lead to severe complication such as gastric ischemia, perforation, and even death. The mortality rate is reportedly 30– 50% (2). Wandering spleen is defined as a movable spleen that can migrate from its normal position to any part of the abdomen or pelvis. Splenic torsion itself is a rare condition with an annual incidence of < 0.2% with or without association of wandering spleen (3). Splenic torsion is potentially fatal, if not urgently managed with surgery. It may cause ischemia, infarction, and even necrosis of the spleen (1). Gastric volvulus and wandering spleen can occur independently. However, these disease entities share a common congenital etiology of anomalous intraperitoneal visceral attachment originating from the dorsal mesogastrium. To our knowledge, only a few cases have been reported previously in literature. Herein, we described a case of gastric volvulus associated with wandering spleen and intestinal non-rotation in a 15-year-old girl, focusing on the multidetector computed tomography (MDCT) findings.
