Computed tomography of the chest, with contrast, shows a heterogeneously enhanced soft tissue mass arising from the right anterolateral sixth rib (yellow arrow), which was eroded and replaced by a portion of the mass that appeared extrapleural. Multiple ill-defined, hyper-attenuating foci in the liver are present, including a larger one measuring 2×1.2 cm in the right lobe and one measuring 2.8 cm×1.4 cm in the gastrohepatic lymph node (yellow triangles).
