There is abnormal, masslike thickening of sigmoid colon with lobulated areas of abnormal enhancement. There is a thin projection of the mass which invades into the bladder wall, with a large polyploid mass extending into the bladder lumen. This dramatic appearance is best appreciated on the coronal and sagittal reformatted images. There are several small, but likely abnormal pericolonic lymph nodes along the pathway of mesenteric venous drainage. There is an approximately 2.0 cm lobulated nodule anterior to the left common iliac artery, likely nodal metastasis.
There are numerous low-attenuation hepatic lesions. Similar lesions which demonstrate lower attenuation are likely cysts. However, several lesions demonstrate intermediate (higher than simple fluid) attenuation and have small, stippled calcifications. These lesions can be seen in hepatic segment II, IV B, and V. Several tiny low-attenuation lesions are too small to characterize.
