Özet:

Pancreatic lipomas are mesenchymal tumors of the pancreas and limited numbers of cases were in the literature. Lesion is asymptomatic unless it is a large mass or it causes compression findings. Because of the limitations in the sonographic evaluation of the pancreas, it can be difficult to detect lesions especially the small ones. In computed tomography (CT) and magnetic resonance imaging (MRI) they have homogeneous internal structure, smooth borders and the same density/intensity as fat tissues at the other parts of the body. They do not enhance, or extend to peripancreatic fat tissue. Fat containing lesions like focal fatty infiltration, teratoma, and liposarcoma are in differential diagnosis. It is important to differentiate from liposarcoma which is malignant. Bigger size (>5cm), heterogeneous internal structure, contrast enhancement and you increasing are in favor of malignity. CT and MRI are very important in detection and differential diagnosis of lipomas.
