Abstract
A 65 years old female visited our hospital with chief complaints of left hypochondralgia and left back pain. Abdominal-ultrasonography showed a cystic lesion in the pancreas body, and a dilated main pancreatic duct. She was hospitalized. She had been going to our hospital because of chronic hepatitis, type c, and diabetes mellitus. In an ERP-CT (Computerized tomography performed immediately after endoscopic retrograde pancreatography) and endoscopic pancreatic biopsy (EPB), under diagnosis of a mucus producing pancreatic adenoma, the pancreatic body and tail (DP), and the spleen were resected. Histological examination of the tumor indicated a mucus producing pancreatic adenoma. As is often the case, the diagnosis of a mucus producing pancreatic tumor was difficult. However, the ERP-CT finding was better than other image diagnoses, so we report it here.
