Pancreatic Lipoma: A Pancreatic Incidentaloma Diagnosis with Computed Tomography.

Lipoma of the pancreas is a rare benign tumour which is usually discovered incidentally on imaging. We present a case of an incidentally discovered pancreatic lipoma in a 79-year-old man with non-metastatic prostate adenocarcinoma who was referred to radiology for follow-up imaging. Fat-containing tumours originating from the pancreas are very rare. Most lipomas show characteristic features on imaging that allow their differentiation. We present the imaging features of a pancreatic lipoma on ultrasound, CT and MRI, discuss the differential diagnosis, and provide a brief review of the literature. LEARNING POINTS: Pancreatic lipoma is a rare mesenchymal tumour that is being increasingly recognized.Pancreatic lipoma is commonly asymptomatic and incidentally detected.CT and MRI allow confirmation of the diagnosis and elimination of other differential diagnoses. © EFIM 2021.
