OBJECTIVE: To assess the feasibility of the prenatal diagnosis using fetal neurosonography of @entity1545 in the surviving fetus after the demise of a monochorionic cotwin. METHODS: This was a retrospective observational study in the period 1990-2004 of monochorionic twin pregnancies with a single fetal demise. A detailed sonographic evaluation of the intracranial anatomy of the surviving twin had been performed whenever possible using a multiplanar approach and from 1999, fetal magnetic resonance imaging was offered as well. Postnatal follow-up was obtained in all cases. RESULTS: In six of nine cases, abnormal neurosonographic findings were identified including @entity932 , @entity1010 , @entity9670 and periventricular echogenicities evolving into @entity8568 . Prenatal diagnosis of @entity75 was confirmed postnatally and all affected @entity1 who survived had severe @entity16 . Two fetuses had normal cerebral structures both on the prenatal neurosonogram and on postnatal imaging and were following normal developmental milestones, one at 1 and the other at 5 years of age. In one case the neurosonographic examination was suboptimal and the @entity1 was found at birth to have a @entity9670 cyst. Fetal magnetic resonance imaging was performed in two cases and confirmed the ultrasound diagnosis. CONCLUSIONS: Prenatal neurosonography is a valuable tool for the prediction of neurological outcome in fetuses surviving after the intrauterine @entity204 of a monochorionic cotwin. Although our experience is limited, we suggest that magnetic resonance imaging should also be offered.

Accurate neurosonographic prediction of XXXX in the surviving fetus after the @entity204 of a monochorionic cotwin.
