Gastric Diverticula: An Uncommon Finding

Clinical Image

Gastric Diverticula (GD) are extremely uncommon. They define as an out pouching of the gastric wall to form a sac-like structure. They can be congenital or acquired and are mostly located on the posterior surface of the gastric fundus.

GD is asymptomatic in general; however, they may present with discomfort or vague abdominal pain. Rarely, GD can be revealed by a complication, such as ulceration, perforation, or hemorrhage.

Abdominal CT scan demonstrates a thin-walled, cystic lesion located in the posterior wall of the fundic region. It may sometimes contain air bubbles or air-fluid level.

Communication with the gastric lumen is easily demonstrated by ingesting a water-soluble contrast.

Differential diagnosis includes adrenal, pancreatic, and renal cysts, duplication cysts, and bowel diverticula.
