title: Gastric diverticulum simulating a left adrenal mass: A case report and review of the literature.
abstract: Gastric diverticulum (GD) is a pouch protruding from the gastric wall. It is rare and in the majority of cases, asymptomatic. Usually GDs are detected incidentally by gastrointestinal study. The current study reports one case and a literature review of GD mimicking an adrenal mass. A 49-year-old male presented with a low-density lesion in the left adrenal area, but no symptoms of an adrenal adenoma. The lesion was identified as a gastric diverticulum in the fundus of the stomach following enhancement of computed tomography (CT) imaging using an oral contrast agent. Although the majority of previously reported cases utilized upper gastrointestinal barium studies to confirm the presence of GD, the current study demonstrated that CT scanning enhanced with oral contrast material may aid in the differentiation of adrenal masses from other gastrointestinal abnormalities.
