Introduction: A gastric diverticulum (GD) is a protruding pouch from the gastric wall and an uncommon anomaly. It is often secondary to traction or dilatation of the gastric wall and is usually asymptomatic. It is rare with a prevalence of 0.12% (2). A GD is often detected on endoscopy or CT and management can range from medical to surgical depending on symptoms. Symptoms often range from mild epigastric pain to nausea, hematemesis, and melena. The following two cases illustrate patients with asymptomatic diverticulum of the gastric fundus discovered on endoscopy. Case 1: 60 year old male with a past medical history of systemic sclerosis, esophageal dysmotility, iron deficiency anemia presented with hematochezia. Endoscopy was performed which revealed a diverticulum of the gastric fundus. (Figure 1,2). CT abdomen on the same visit did not reveal a gastric diverticulum.Figure 1Figure 2Case 2: 69 year old male presented with atypical chest pain and gastroenterology was consulted after a negative cardiac workup. Patient reported stabbing chest pain not associated with eating and lasted 20-30 seconds associated with intermittent non-bloody diarrhea with 3-4 bowel movements per day. EGD the next day revealed a diverticulum in the fundus and erythema of the body of the stomach with some concern for gastric Crohn's (Figure 3). Biopsies however were unremarkable.Figure 3Discussion: Diverticula of the gastric fundus are rare. Symptoms may range from mild epigastric pain to severe complications such as hemorrhage and perforation. A gastric diverticulum can be misdiagnosed as an adrenal mass on CT or may harbor malignancy that can be seen on endoscopy (1). These cases illustrate the important role of endoscopy in diagnosis and visualization and emphasize that a careful exam of the whole stomach including the fundus is necessary to characterize diverticula as benign or malignant. This case also illustrates a role for CT which may not always reveal a diverticulum as in case 1. Unlike a CT scan, endoscopy allows for direct visualization, biopsy and intervention as necessary and can often determine if medical or surgical management is needed.
