Complete hydatidiform mole with a coexisting twin live fetus (CHMTF): the uncommon diagnostic enigma—simplified.

Background: Twin pregnancy comprising of a complete hydatidiform mole with a coexisting twin live fetus is an uncommon condition with an incidence rate of 1 in 20,000 to 1 in 100,000 pregnancies, more so in assisted reproductive technologies. The primary diagnosis is made on ultrasound and adjunct fetal MRI helps in unequivocally differentiating it from other disorder. Case presentation: We present a case report of a twin pregnancy consisting of complete hydatidiform mole with a coexisting twin live fetus in a 27-year-old primigravida conception, primarily focusing on its diagnostic algorithm and related clinical aspects, adding to the paucity of existing literature. Conclusions: Following the correct diagnostic algorithm with imaging studies like USG and more importantly MRI, combined with the bioclinical picture helps in reaching the accurate diagnosis.
