A huge pancreatic lipoma mimicking a well-differentiated liposarcoma: A case report and systematic literature review

Figure 1 Computed tomography scans before treatment. A: Non-contrast abdominal computed tomography (CT) showed a 6.4 cm × 6.0 cm, nearly circular, heterogeneous lesion, owning indistinct borders, located in the head of the pancreas. B: Contrast-enhanced CT imaging indicated that the fat containing tumor (-109 ± 19.2 HU in the tumor and 47.9 ± 14.9 HU in the liver) had a few fibroreticular septa within it, and the surrounding parenchyma of the mass could be slightly enhanced (arrow).
