Ovarian endometrioid adenocarcinoma and sertoliform endometrioid adenocarcinoma belong to the surface epithelial-stromal tumors. Sertoliform endometrioid adenocarcinoma is an uncommon variant, and comprises a portion resembling endometrioid adenocarcinoma and a portion resembling sex-cord stromal tumor. The aim of this study was to investigate differential imaging features between ovarian endometrioid adenocarcinoma and sertolifolm endometrioid adenocarcinoma on magnetic resonance imaging. In quantitative assessment, SIR values of sertoliform endometrioid adenocarcinoma reflecting T2-low signal intensity yielded low values than those of endometioid adenocarcinoma. MR imaging findings of endometrioma were more likely endometrioid adenocarcinoma, whereas SIR of seltoliform ednometrioid adenocarcinoma yielded low values.
