ABSTRACT
Objective To discuss the imaging findings of the sex cord-stromal tumors of ovary.Methods The pathologically confirmed CT and MRI images of 69 patients with sex cord-stromal tumors of ovary were collected retrospectively.Results Among 69 cases of ovarian sex cord-stromal tumors,there were fibrothecoma 3 1 cases,thecal cell tumor 1 9 cases,fibroma 1 2 cases,granulosa cell tumors 5 cases and stromal sarcomas 2 cases.CT and MRI had detected all the 69 tumors.Most of the tumors (52 cases,accounting for 75%)were presented as mainly solid tumors combined with cystic changes,some (13 cases,accounting for 19%)were presented as all solid and a few cases (4 cases,accounting for 6%)were presented as cystic tumors.The tumors were round or oval,with clear boundary,which showed low density,and either no obvious enhancement or mild delayed enhancement on CT scan.The solid part of tumors showed low signal on T2WI and slightly higher signal on diffusion weighted imaging(DWI).Conclusion The sex cord-stromal tumors of ovary are mainly solid tumors combined with cystic changes,with clear boundary,either with no obvious enhancement or mild delayed enhancement and low signal on T2WI and slightly higher signal on DWI.The study shows that the above imaging features are helpful to improve the diagnostic accuracy of sex cord-stromal tumors of ovary.
