“…GD can be classified into two types – congenital, or true, diverticula and acquired, or false, diverticula – with congenital diverticula being more common [3, 11-15]. True diverticula contain all layers of the gastric wall.…”

Gastric Diverticulum: A Comprehensive Review

Background: Gastric diverticula (GD) are outpouchings of the stomach wall that typically form in the fundus. They are the least common gastrointestinal diverticula, and are very rare anatomic abnormalities overall. Summary: Although most GD are asymptomatic and are usually discovered incidentally during routine diagnostic testing, they can present with variable symptoms. Occasionally, complications can develop that may be life-threatening and are indications for surgical management. Key Messages: Here, we provide a literature review of GD where we discuss the pathogenesis, clinical manifestations, investigations and diagnostic approach, and various management options for this uncommon disorder.

Computed tomographic (CT) findings in 105 cases of pancreatitis and 107 cases of pancreatic carcinoma were analyzed retrospectively to determine the occurrence and roentgenologic signs of penetration of the anterior renal fascial planes in relation to clinical symptoms. In pancreatitis, the perirenal fat was infiltrated in 7% to variable extents by extrapancreatic fluid collections, either as asymptomatic fluid lying alongside renal fascial planes and perirenal septa (5 cases) or as well-circumscribed fluid collections causing clinical symptoms (2 cases). In pancreatic carcinoma the occurrence of retropancreatic extension to a perirenal space was rarer (3%). Distinction on CT between perirenal involvement from the pancreas and primary adrenal or renal lesions with anterior spread can prevent unnecessary surgery.

“…In the embryonic stages of gastrointestinal development, rotation of the stomach leads to forming the duodenal loop, the pancreas, and the mobile dorsal mesentery. When the posterior-body wall and dorsal mesentery fuse, the pancreas is encapsulated within the retroperitoneal region, wherein a diverticulum of the posterior wall of the gastric cardia may be herniated through an area of dorsal mesentery [24,25]. If the migration of diverticulum occurs before renal ascent, the diverticulum could indent Gerota's fascia and stay between the left kidney and the left adrenal gland [10].…”

Gastric Diverticulum Simulating Left Adrenal Incidentaloma in a Hypertensive Patient

et al. 2007

Abstract.A 46-year-old Japanese male with hypertension was referred for examination of left adrenal tumor incidentally detected by computed tomography (CT) scan. The patient had a 4-month history of hypertension. Abdominal CT demonstrated a low-density mass 2.5 cm in diameter in the left adrenal region that was observed as a high-intense lesion with T2-weighted magnetic resonance imaging. 131 I-adosterol scintigraphy showed normal uptake of bilateral adrenals. The adrenocortical hormone levels were within normal ranges; however, urinary noradrenaline excretion was slightly elevated, likely due to concurrent sleep apnea syndrome. Based on the observation of a very tiny bubble in the ventral portion of the adrenal mass by careful review of CT images examined at a previous hospital, a restudy of abdominal CT with oral contrast was performed. In this restudy abdominal CT we observed positive enhancement of the left adrenal mass, indicating that the adrenal mass was a diverticulum derived from posterior gastric fornix. The present case study reinforces that preoperative differentiation from mimic adrenal tumors is necessary in cases of cystic adrenal mass in the left adrenal region.
