Intestinal duplications are rare and are usually diagnosed in the firs t two years of infancy. They can occur at any level of the alimentary tract from the oral cavity to the anus. Duodenal duplication accounts for approximately 7% of all intestinal duplications. A previously heal thy 4-year 6-month old boy was admitted with progressive increasing vo miting. Physical examination was normal, the serum amylase level was m oderately increased. Upper gastrointestinal series showed an extrinsic compression defect of the proximal duodenum. Ultrasonography showed a 3 cm diameter cyst in the head of the pancreas. A duplication was sug gested. Helical CT cholangiography showed a communication between dupl ication and the biliopancreatic common channel. The biliary tree was n ormal. Surgical resection of the intrapancreatic lesion was performed. Microscopic examination of the specimen revealed a duodenal duplicati on.
