Fetal ovarian cysts commonly present as anechoic, thin wall and unilateral cyst. Intracystic bleeding is rare and mostly suspected by ultrasonographic presentation. All previous reported case occurred at late third trimester of pregnancy and all infants were delivered normally with fetal ovarian tumor with hemorrhage as the diagnosis. Thus, a sequence of ultrasonographic appearance for fetal ovarian cyst complicated with spontaneous intracystic bleeding has never been reported. Herein, the ultrasonographic appearance for fetal ovarian cyst complicated with spontaneous intracystic bleeding sequencing in a 3-weeks period was reported.
