Calcified intraperitoneal metastases from ovarian carcinoma

Three cases of calcified ovarian metastatic carcinoma are reported in order to illustrate their principal forms and distribution. These cases also demonstrate unusual features of serosal, colonic, and gastric invasion; ureteral obstruction by a calcified metastasis; and active uptake of technetium diphosphonate by the metastatic lesions. Plain films often simulate retained colonic barium.
