Example of mucinous regression of a metastasis of non-otherwise specified (NOS) adenocarcinoma of the rectum in a 52-year-old male patient treated by chemotherapy followed by hepatic resection. On preoperative MR imaging the lesion (arrows) shows high signal intensity on the fat-saturated fast spin echo T2-weighted image (a) and the diffusion weighted image (b 800 s/mm2) (b). The apparent diffusion coefficient was high (c). Gross pathology (d) shows a polylobated metastasis with central mucinous regression, containing lakes of acellular mucine (arrowhead)
