A rare case of spontaneous live unilateral twin tubal pregnancy with both fetuses presenting with heart activities and a literature review

Abstract

Ectopic pregnancy is an extrauterine pregnancy, and 98% of which occur in the fallopian tube. The incidence of twin tubal pregnancy is rare but is increasing due to assisted reproductive technology. Spontaneous unilateral twin tubal pregnancy is extremely rare, and only a small number of case reports have been made. We herein report a rare case of spontaneous unilateral twin tubal pregnancy with both fetuses presenting with heart activities and a literature review. Right salpingectomy was performed in this case. Pathologic and histologic assessment confirmed the 2 distinct pregnancies in the same tube. The twins were dichorionic and diamniotic.
