Case Report


Conjoined twinning is a very rare occurrence with no genetic predisposition. Twisting of conjoined twins around the axis of their connecting tissue bridge, close to the third trimester, has not been previously reported. We describe a unique case of in utero twisting of conjoined omphalopagus twins who survived without any adverse effects. Fetal US and fetal MRI played a vital role in the diagnosis and perinatal management of these twins.
