A 50 -year-old female had undergone resection of Isp type polyp (26 × 18 × 15mm) in the rectum under colonoscopy. Histopathological diagnosis of the resected polyp was mixed type polyp of carcinoid with massive submucosal invasion. Preoperatively, EUS, CT and MRI showed one swollen lympn node (251R) and two swollen lymph nodes located along the internal iliac artery (262R). Therefore, super low anterior resection with level 3 lymph node dissection was performed, resulting in absolute curative resection. Rectal Carcinoids more than 20mm in diameter frequently have metastases of regional lymph nodes, therefore, adequate lymph node dissection is required. Preoperative EUS, CT and MRI are useful for diagnosis of regional lymph node metastasis of rectal carcinoid.
