Key Clinical Message:
Gastric diverticulum in the posterior wall of the stomach is very rare, and it is easy to be misdiagnosed as a left adrenal mass on imaging. Therefore, we must consider the possibility of gastric diverticulum when diagnosing a left adrenal mass.
Abstract:
This paper reports a case of gastric diverticulum that was misdiagnosed as a left adrenal mass on abdominal enhanced CT. The patient underwent laparoscopic adrenalectomy, but there was no mass in the left adrenal found during surgery. After the incision of the retroperitoneum, a cystic mass was found adjacent to the posterior gastric wall which turned out to be gastric diverticulum. This case suggests that gastric diverticulum, a rare disease, may be interpreted as an adrenal mass on imaging. Therefore, as a urologist, the gastric diverticulum must be excluded when CT suggests a mass in the left adrenal region.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
