Multicystic encephalomalacia after first-trimester intrauterine fetal death in monochorionic twins

A case report of multicystic encephalomalacia after the demise of a cotwin in the first trimester diagnosed by magnetic resonance imaging and confirmed pathologically is presented. It is observed that multicystic encephalomalacia occurs in almost 20% of the surviving cotwins after the second-and third-trimester intrauterine fetal death of one twin in monochorionic pregnancies.
