Objective To investigate the MRI findings and clinical features of adult granulosa cell tumor of the ovary,and to improve the diagnostic ability of adult granulosa cell tumor of the ovary.Methods MRI findings and clinical data of 19 cases of adult granulosa cell tumor confirmed by surgery and pathology were retrospectively analyzed.Results The average age of the 19 patients was 44.4±11.5 years,including 12 non-menopausal patients with an average age of 37.6±7.7 years and 7 menopausal patients with an average age of 57.3±2.4 years.18 patients had clinical symptoms,mainly including irregular menstruation and postmenopausal vaginal bleeding.11 patients had hormone laboratory tests,which 72.7％estrogen levels were increased and follicle stimulating hormone levels were all decreased.MRI showed unilateral mass in 18 cases and bilateral masses in 1 case,most of which showed multiple cystic foci and bleeding signal.On T1WI,most masses were hypointensity and bleeding signal was visible in 80％cases.On T2WI,masses mainy showed hyperintensity and 85％cases showed"honeycomb sign"and"sponge sign".Conclusion The combination of MRI features and clinical features of adult granulosa cell tumor is of great significance for improving the preoperative diagnosis.
