A 32-year-old female was found to have a cystic mass of the pancreas head and was admitted to examine the operability. Just prior to admission endoscopy was performed and revealed only an extracompression of the antrum and duodenum. But during the admission, anemia progressed in a few days. In order to detect the bleeding point, 99mTc scincygraphy was performed and indicated the bleeding from the duodenum. Endoscopy revealed an ulcerative lesion in the bulb of the duodenum as bleeding point. After pancreatico-duodenectomy, it became clear that the ulcerative lesion of the duodenum was a part of pancreatic cystadenoma which perforated in to the bulb. Perforation of pancreatic cystadenoma into the duodenum is uncommon and it is much rarer that perforated cystadenoma canses gastrointestinal bleeding.
