A 67-year-old woman with papillary serous ovarian adenocarcinoma. Axial contrast-enhanced CT performed at the start of chemotherapy shows an enhancing soft-tissue nodule in left paracolic gutter (arrow on left) with a punctate focus of calcification (arrowhead), compatible with a peritoneal implant. After 8 months of chemotherapy, follow-up contrast-enhanced CT demonstrates increased density of the calcification and decreased size of the left paracolic gutter nodule (arrow on right), indicating that increasing density of calcification may be associated with a treatment response.
