Abstract: Objective To assess the value of MRI combined with CT in the diagnosis of ovarian sex cord stromal tumor (OSCST).Methods The CT and MRI features of 29 cases with OSCST confirmed by pathology were analyzed retrospectively.Results Fibrothecoma in 19 cases showed a solitary round mass with a regular border,solid in 12 cases (63.1％) and cystic-solid in 7 cases (36.9％),calcification in 2 cases,isointense on T1WI and hypointense or slight hyperintense on T2WI with slight enhancement.Granule cell tumor in 9 cases showed a solitary cystic solid mass with thick wall,without nodules on cystic wall,and slight enhancement in the solid parts.Sertoli-leydig cell tumor in 1 case showed a solid mass,slightly hyperintense on T1WI,hyperintense on T2 WI,and obvious enhancement.Conclusion CT and MRI manifestations of OSCST demonstrate some characteristics.Combination with MRI and CT can improve the accuracy of the diagnosis.
