Coronal CT imaging. Coronal CT imaging showed a large mass occupying most of the lower portion of the right abdomen with a dyshomogeneous density due to cystic and necrotic areas and no infiltration of the surrounding tissues (a). The tumor is located near the omolateral outer iliac vein as well with secondary dislocation and suspect infiltration (b). In the PET/CT imaging, the central photopenic portion of the mass might reflect necrotic process (c).
