ABSTRACT
We report a 62-year-old female with chronic pancreatitis after three episodes of severe acute pancreatitis. In 2008, an uneven main pancreatic duct (MPD) of 16 mm was found during an abdominal ultrasound. The follow-up was not continued until 2020, when a dilation of 27 mm of the MPD was discovered at magnetic resonance imaging (MRI). In 2022, another radiological test was carried out showing a dilation of the MPD of 40 mm with an intraductal tumoral lesion of 30 mm at the head of the pancreas). An echo-endoscopy was carried out and a pancreatic-duodenal tumour with a mixed pattern was discovered. Atypic cells were observed at the fine needle punction. A total duodenopancreatectomy was successfully carried out. In the anatomopathological macroscopic study a 14 cm-multi-cystic neoformation was seen and a solid tumour was discovered at the head of the pancreas that infiltrated the wall of the duodenum. In the longitudinal cross-section of the pancreatic body the MPD was seen to be severely dilated. A focal adenocarcinoma in a intraductal papillary mucinous neoplasm (IPMN) was finally diagnosed. Pancreatic lesions are usually asymptomatic and are detected by chance during other imaging tests. The IPMN rates of malignancy have been reported of between 19 to 30%. The management of pancreatic cystic lesions still represents a clinical challenge. As always, the multi-disciplinary management is mandatory in this type of tumour.
