Carcinoid tumors arising in the duodenum are uncommon. We reported a case ofduodenal carcinoid evaluated by endoscopic ultrasonography with intraductal catheter probe. A 68-year-old man was admitted to our hospital in May 1993 with nausea. Endoscopic finding showed a small elevated lesion with slight depression on the anterior wall of the duodenal bulb. Biopsy specimen taken from the lesion revealed carcinoid tumor. Endoscopic ultrasonography (EUS) with intraductal catheter probe (20MHz) revealed a hypoechoic tumor with regular margin in the second-third layer of the duodenal wall. The tumor, measuring 6. 4mm in size, was removed by surgical operation. The tumor was located in the duodenal submucosa. EUS with intraductal catheter probe was thought to be useful for the diagnosis of the extent and depth of invasion of a small duodenal carcinoid tumor.
