Complete molar pregnancy with coexisting normal twin complicated by hyperthyroidism that resulted in normal alive delivery: A case report from Wolaita Sodo, Ethiopia.

It is a rare condition in twin pregnancies for a fetus to coexist with a complete hydatidiform mole, present with complications, and result in a healthy neonate. Only a few cases have been reported upon review of the literature. Early diagnosis is essential because this type of pregnancy is associated with serious complications and management challenges. The complications associated with these pregnancies include antepartum hemorrhage, hyperthyroidism, preeclampsia, prematurity, fetal death, and gestational trophoblastic neoplasia. Here, we describe a case of dizygotic twin pregnancy in which a complete mole coexists with a normal fetus, complicated by hyperthyroidism, that resulted in the birth of a 1700-g female alive neonate who is euthyroid to a 25-year-old primigravida at a gestational age of 33 weeks by emergency cesarean section for an indication of a twin pregnancy molar coexisting with an alive fetus in labor. The mother had been on conservative management and treated as an inpatient for hyperthyroidism. In our country, there have been three case reports of partial moles with coexisting alive fetuses, but this is the first case report of a complete mole with a coexisting alive fetus.
