Background
Tumors of the small intestine are rare. Among all such tumors, about 25% are benign, with smooth muscle tumors as the most frequently detected type. Generally, adenomas are commonly seen in the large intestine whereas those in the small intestine, accounting for about 10% of the benign tumors, are rarely encountered endoscopically. While the duodenum is the most frequently involved site, an ileal adenoma is extremely rare. During colonoscopy, intubation of the terminal ileum remains controversial, as the diagnostic value is limited [1]. Moreover, it is often technically difficult to reach the terminal ileum, especially when patients are in a lateral position.
