A Retrospective Study of a Case with Pancreatic Lipoma
Introduction Pancreatic Lipoma is one of the rare benign mesenchymal tumors representing 1 to 2% of all pancreatic tumors and should be differentiated from liposarcoma, teratoma and focal fatty infiltration. Case Report A 54-year-old female was found to have an incidental finding of a well-defined 1 cm homogenous mass in the junction of body and tail of pancreas during a routine Computed Tomography scan for a nonspecific abdominal pain and constipation. The lesion was of a low density (-50 HU) consistent with fat. Subsequent Magnetic Resonance Imaging revealed a well-defined homogenous mass with a measurement of 1.0 × 0.7 cm with high signal intensities in both T1 and T2 weighted sequences and fat suppression in fat suppressed sequences confirming the fatty nature of the lesion. Therefore, a diagnosis of pancreatic lipoma was made based on the signal characteristics of the lesion. Conclusion Pancreatic lipoma has characteristic features on diagnostic imaging modalities and biopsy to confirm the diagnosis is rarely needed.
