Complete or partial agenesis of dorsal pancreas has been reported in a small number of pediatric and adult patients. A case of partial agenesis of dorsal pancreas was reported. This case was not associated with diabetes mellitus and pancreatic exocrine dysfunction, or abdominal pain. A 37-year-old man with chronic hepatitis B visited to our hospital due to further examination for chronic hepatitis B. Abdominal ultrasonography showed enlarged pancreatic head. Diagnosis was made by endoscopic retrograde cholangiopancreatography and computed tomography. Explor-laparotomy was not done.
