Bleeding Isolated Gastric Varices as a Rare Presentation of Pancreatic Neuroendocrine Tumor: Case Report and Literature Review.

Isolated gastric varices (IGV) are gastric varices in the absence of esophageal varices. IGV is one of the rare causes of gastrointestinal bleeding and an uncommon complication of pancreatic neuroendocrine tumors (PNET). The gold standard diagnostic tool of varices is esophagogastroduodenoscopy (EGD). IGV tend to bleed with lesser portal pressure compared to esophageal varices. Initial treatment is similar to the gastroesophageal varices. The intervention options include endoscopic, radiological, and surgical approach.
