Abstract

<p>A 59-year-old asymptomatic woman was found to have a cystic mass in the tail of the pancreas during a periodic health examination and was referred for further evaluation. A 5 × 3cm multilocular lesion was seen on contrast-enhanced computed tomography scan. The central part of the lesion was solid and deeply enhanced in the early phase and surrounded by larger multi-lobed cysts. The lesion was also recognized to have multi-lobed cysts with high intensity on T2-weighted images of MRI and MRCP. Intra-cystic nodules and a honeycomb-like area were seen on endoscopic ultrasound imaging. One of the pancreatic cysts appeared to communicate with the main pancreatic duct using endoscopic retrograde pancreatography. Cytology of the pancreatic fluid did not show malignant cells. Distal pancreatectomy and splenectomy was performed. Histopathological evaluation showed a serous cystic neoplasm (SCN, microcystic type) and intraductal papillary neoplasm (IPMN, gastric type) located next to each other. Synchronous pancreatic SCN and IPMN are extremely rare. This paper reports our experience together with a review of the literature and comment.</p>
