Liposarcoma. a Coronal CT image post contrast demonstrates a large low attenuation mass (fatty) located in the left upper hemithorax. The mass contains a heterogeneous area increased density/soft tissue component in the superior aspect of the mass (arrow), a finding which is suspicious for a liposarcoma. b Coronal T1WI MR images of the same lesion demonstrating a hyperintense mass in the left hemithorax with areas of heterogeneous low signal in the upper aspect of the mass (arrow). c Coronal FDG-PET/CT of the same lesion showing mild increased hypermetabolism in the area of heterogeneous enhancement within the fatty mass (arrow)
