Introduction
Twin pregnancy with complete hydatidiform mole and
coexisting fetus is rarely seen during clinic practice. The
incidence ranges from 1 in 20,000 to 1 in 100,000 pregnancies
[1]. Diagnosis in such cases can be simply made
by obstetric ultrasound examination but the decision
whether to conserve or not is always problematic. Traditionally,
termination of pregnancy was indicated to avoid
the unacceptable risk of complications of complete
molar pregnancy such as early onset pre-eclampsia,
thyrotoxicosis and increased risk of persistent trophoblastic
disease [2].
