Endovaginal sonography has permitted earlier diagnosis of ectopic pregnancy. Twin ectopic pregnancy is rare. Until now, antenatal diagnosis of twin ectopic pregnancy using endovaginal sonography had not been reported. Three cases of twin ectopic pregnancy diagnosed via the intracavitary probe are presented.
