Abstract:
Dynamic CT of a 53-year-old man revealed a slightly hyperdense tumor at an arterial phase, and it was much enhanced 3.5 min later. Since the histology of the resected specimen revealed tumor thrombi of the vein around the tumor, this sign is probably based on delayed washout of the contrast media from the tumor.
