CT findings of sclerosing stromal tumor of the ovary: A report of two cases and review of the literature.

Abstract

Sclerosing stromal tumor (SST) of the ovary, which was first described by Chalvardjian and Scully in 1973, is a rare ovarian neoplasm, occurring predominantly in young women. The most common clinical symptom in patients with SST is menstrual irregularities. Microscopically, the tumor is characterized by the presence of pseudo-lobulated cellular areas, with a prominent tendency to sclerosis, marked vascularity and pronounced variation in cellular size and shape. In the current study, 2 cases of SST of the ovary are presented. These cases were confirmed by imaging, surgical and histological examination. No adjuvant therapy was administered to the patients and the two patients were disease-free with no imaging findings of recurrence or metastasis 24 months following surgery.
