Intrauterine fetal death of one of twins, coexisting with hydranencephaly in the surviving co-twin: A case report

Abstract

Hydranencephaly, a relatively rare malformation of the brain, is characterised by absence of the cerebral hemispheres and their replacement by sacs filled with cerebrospinal fluid. It is one of the recognised forms of intracranial malformations associated with intrauterine fetal demise of one of twins in monochorionic twin gestation. This report illustrates the development of hydranencephaly in a surviving twin sequel to intrauterine fetal demise of the co-twin.
