Serous psammocarcinoma is a rare subtype of serous carcinoma in which a significant number of psammoma bodies are present histologically. Because it is an extremely rare disease, the pathogenesis of the disease remains unclear. Here we present a case of primary ovarian serous psammocarcinoma in which computed tomography (CT) imaging of the abdomen was useful for the diagnosis.

A female patient was referred to our department with a complaint of abdominal distention. Pelvic magnetic resonance imaging revealed a multifocal tumor with a papillary enhancement in the right appendicular region, and abdominal CT imaging exhibited marked calcification of the enhancement. She underwent a laparotomy for suspected right ovarian cancer. As postoperative pathological examination revealed dominant stromal infiltration of psammoma bodies beneath peritoneum, this case was diagnosed as primary ovarian serous psammocarcinoma at FIGO Stage IIB. The patient was treated with six courses of paclitaxel plus carboplat in after the surgery. She is currently under outpatient observation without any signs of recurrence after 8 years of treatment. The case of significant calcification of the intra cystic enrichment on CT imaging is considered to be a case of this disease.
