A 54-year-old woman with squamous cell carcinoma of the rectum. (a,b) Contrast-enhanced portal venous phase CT images demonstrate an infiltrative, heterogeneously well-enhanced bulky mass (arrows) in the upper rectum with central necrosis (asterisk) and invasion of the uterus. CT images also show multiple large metastatic lymph nodes (arrowheads) with some central necrosis (curved arrow). (c) The contrast-enhanced portal venous phase CT image depicts multiple peripheral well-enhanced metastatic nodules (arrows), with some central necrosis (asterisk) in both hepatic lobes.
