Oncocytic intraductal papillary neoplasm of the pancreas: Multimodality imaging and cytopathologic correlation

Intraductal oncocytic papillary neoplasm of the pancreas (IOPN-P) is a rare cystic epithelial tumour with distinctive imaging, cytological and histological features. This case report describes a 65-year-old female who presented with abdominal pain and vomiting for 6 months and was later diagnosed with IOPN-P. Multimodality imaging, including ultrasound, contrast-enhanced CT, MRI, MRCP and endoscopic ultrasound, played an important role in lesion evaluation. Cytopathological evaluation and immunohistochemistry confirmed the diagnosis.

The case highlights the importance of recognising radiological features of IOPN-P to differentiate it from more aggressive pancreatic neoplasms.
