ABSTRACT
Sclerosing stromal tumor of the ovary is a rare benign sex-cord stromal tumor that affects primarily young females. In a series of six patients (mean 24,6, median 19 years) findings of six MRIs and one CT were analyzed. Unilateral tumors ranging from 6 to 8 cm were found in all patients. The tumors were well encapsulated and polylobulated. The morphology was mixed solid and cystic in three and solid in three patients. In CT, a hypervascular tumor with centripetal enhancement was seen. In MRI T 2 weighted imaging showed low signal intensity of the solid tissue in all cases and low diffusion-weighted imaging signal of the solid tissue in high b-value diffusion-weighted imaging in three patients. Contrast enhancement was avid with extension from the periphery in all patients. Knowledge of these distinct radiological features of sclerosing stromal tumor is important, as in the Ovarian-Adnexal Reporting and Data System risk classification system this may be scored as Ovarian-Adnexal Reporting and Data System 5. Because of its non-aggressive clinical course, pre-operative imaging assists to avoid unnecessary extensive surgery and to preserve the patient's fertility by only resecting the tumor and preserving the ovary. Sclerosing stromal tumor of the ovary presents pathognomonic features in MRI that allow a specific pre-operative diagnosis and selecting candidates for fertility-sparing surgery.
