Although a few had been documented worldwide, none has been reported in Nigeria. In this report, we document the history of a concoction of drugs of an indeterminate nature taken in pregnancy, the wrong diagnosis by the rural based sonographer and the presence of polyhydraminos. Our finding of a previously misdiagnosed oropharyngeal fetus-in fetu with dichorionic and cardiac features calls for a revision of the current definition of fetus-in fetu. It also raises an important hypothesis of the likely associations between drugs, infections, pregnancy induced hypertension and fetus-in-fetu. ER -
