# Rare Gastric Diverticulum Mimicking Adrenal Abscess on Computed Tomography

## TL;DR

A rare case of a gastric diverticulum was mistaken for an adrenal abscess on CT scans, highlighting the need for accurate diagnostic methods.

## Contribution

This case report highlights the diagnostic challenge of gastric diverticula mimicking adrenal abscess on CT.

## Key findings

- Gastric diverticula can mimic adrenal masses on CT due to their anatomical proximity.
- The case showed apparent infection spread to the lung, complicating the diagnosis.
- Upper gastrointestinal series or endoscopy are more reliable for diagnosing gastric diverticula.

## Abstract

Gastric diverticula are a rare phenomenon that is typically asymptomatic and encountered incidentally. Due to the relative proximity between the gastric diverticula and the left adrenal gland, they may mimic adrenal masses on computed tomography (CT). For this reason, the preferred diagnostic methods for gastric diverticula are upper gastrointestinal series or direct visualization on endoscopy. The present report describes an unusual case of a gastric diverticulum mimicking an abscess of the adrenal gland with the apparent spread of infection to the left lower lobe of the lung.
