case_images: Sagittal image from contrast enhanced CT demonstrating a 6.9 cm rim calcified cyst (see Arrow) arising from the dome of the urinary bladder (labelled "B") corresponding to a urachal cystic tumor of low malignant potential. Immediately posterior to this is the 6.5 cm sigmoid colon adenocarcinoma (labelled *), represented as circumferentially thickened bowel with luminal narrowing and irregular serosal surface seen in cross-section.
