AbstractEctopic varices include all varices except esophageal or gastric varices and comprise large portosystemic venous collaterals that occur anywhere in the abdomen. Ectopic varices are relatively rare; however, approximately 5% are related to gastrointestinal bleeding. Ectopic varices usually occur in the rectum, duodenum, or colon, and portal hypertension is the most common cause. Hemodynamic profiles of ectopic varices remain unknown, and extensive bleeding from these structures occurs because diagnosis and treatment are difficult. Here we report a case of obscure gastrointestinal bleeding (GIB) due to ectopic varices in the small intestine that flowed into the inferior epigastric vein. Our observations suggest that when obscure GIB is detected in patients with either cirrhosis or post-surgical history including incisional hernia, it is essential to acquire multilanar reconstruction images and volume-rendered 3-dimensional reconstruction of computed tomography scans to investigate the complex venous supply and optimize decisions for therapy.
