Serous psammocarcinoma of the ovary: CT and MR findings.

Serous psammocarcinoma, a rare variant of ovarian serous carcinoma, is characterized histologically by the pervasive presence of psammoma bodies. In this case, computed tomography scans showed extensively calcified pelvic and peritoneal masses. The pelvic mass appeared sandy on enhanced T1-weighted magnetic resonance images. These imaging results suggest that the presence of abundant psammomatous calcifications in primary and disseminated lesions may be a radiological marker of ovarian psammocarcinoma.
