Holoprosencefalia. Papel de la resonancia magnética en el diagnóstico prenatal

We presented a case affected of trisomía 13 and fetal malformations. Prenatal sonography and magnetic resonance imaging were performed. The fetus suffered semilobar holoprosencephaly, craniofacial malformations and tetralogy of Fallot. A review of sonographics and magnetic resonance findings is presented emphasizing the role of magnetic resonance as a complemmentary imaging technique when sonography has diagnostic limitations.
