Abstract

ResumenLa lisencefalia es una malformación cerebral caracterizada por la ausencia (agiria) o reducción (paquigiria) de las circunvoluciones cerebrales, causado por una migración neuronal anómala en el neocórtex. Presentamos un caso de sospecha ecográfíca prenatal de feto afectado de lisencefalia, confirmado mediante resonancia magnética posnatal. El recién nacido presentó una dismorfia facial característica y el cariotipo con estudio FISH una deleción del cromosoma 17p13.3, lo que nos llevó a un diagnóstico definitivo de síndrome de Millar-Dieker.

Lissencephaly is a cerebral malformation characterized by the absence (agyria) or reduced number (pachygyria) of convolutions, caused by a failure of neuron migration in the neocortex. We present the case of a fetus with a suspected diagnosis of lissencephaly based on prenatal ultrasound, which was confirmed by postnatal magnetic resonance imaging. The newborn showed characteristic facial dysmorphism, and cytogenetic analysis with FISH studies showed a deletion of a region at chromosome locus 17p 13.3, leading to a definitive diagnosis of Miller-Dieker syndrome.
