Lipoma of the Pancreas: A Rare Incidental Tumor.

ABSTRACT

Recent studies have shown a significant increase in the utilization of computed tomography (CT) scans in the emergency department for a broad spectrum of conditions. This had a significant impact on the identification of patients with serious pathologies in a timely manner. However, the overutilization of computed tomography scans leads to increased identification of incidental findings. For example, pancreatic lesions are not uncommon findings that can be identified in imaging studies performed for other indications. Here, we report the case of a 55-year-old male with a history of urinary stone disease who presented with right flank pain and dysuria. The urinalysis findings revealed numerous red blood cells and leukocytes. Non-contrast computed tomography scan of the abdomen was performed to detect urinary stones, but no hyperdense stones were noted, suggesting the possibility of spontaneous passage of the stone. However, a lesion in the pancreatic tail was observed. This exhibited fat attenuation with no solid component in the pancreatic tail representing a pancreatic lipoma. No surgical intervention was made considering the benign nature of the incidentally detected tumor. Pancreatic lipoma is a very rare benign mesenchymal tumor of the pancreas. Recognition of the classic radiological feature of pancreatic lipoma is essential to avoid unnecessary investigation and procedures.
