Spectrum of Atypical Vascular Pathologies Mimicking Duodenal Submucosal Tumor and Directly Bleeding into Duodenal Lumen: A Case Series Study with Management by Interventional Radiology

Abstract Gastrointestinal (GI) bleeding is a life-threatening medical condition and requires a multidisciplinary approach for proper diagnosis and management. Various vascular pathologies in and around the duodenum can lead to bleeding into the duodenum either directly or through the bile duct or pancreatic duct, and the patients present with melena or hematemesis. Sometimes, these lesions present as a submucosal tumor with active bleeding or present like a bleeding duodenal ulcer. These cases must be investigated thoroughly before any endoscopic interventions; otherwise, patient may land up in life-threatening situations. Radiology plays an important role in both diagnosing and treating these vascular lesions. Here, we have presented a few cases where the vascular pathologies mimicking duodenal submucosal tumors caused direct bleeding into the duodenum.
