Abstract

A 71-year-old woman who experienced abdominal discomfort visited our hospital. Abdominal ultrasonography showed 2 cystic lesions in both the body and the tail of the pancreas. The patient underwent follow-up for 6 months, after which a computed tomography (CT) scan showed slight enlargement of the pancreatic tail. Several imaging tests “(endoscopic ultrasonography, CT, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography).” showed 2 multilocular cystic tumors. The size of the tumors was 22.5 × 19 mm (body) and 17.5 × 16.5 mm (tail). However, it was difficult to form a definitive diagnosis. Surgical resection was performed after a clinical diagnosis of intraductal papillary mucinous neoplasm (IPMN) (body) and mucinous cystic neoplasm (tail). The final diagnosis was IPMN (body) and multilocular cyst-forming glucagonoma (tail). IPMN is associated with various tumors. It is necessary to check for the presence of endocrine tumors, even in patients with cystic tumors.
