RESUMEN

Introducción. Existen pocos reportes de neonatos vivos de ‹500g con retardo en el crecimiento intrauterino (RCIU).
Caso clínico. Se reporta el caso de un recién nacido con RCIU grave, madre de 30 años, primera gesta, 31 semanas de gestación y oligohidramnios grave, obtenido por cesárea, femenino, de 480 g, talla 30 cm, Apgar de 7-7, recibió oxígeno al 80% por 48 horas y, a partir de entonces, se inicia vía oral y nutrición parenteral. Las IgG e IgM para citomegalovirus y cuerpos de inclusión citomegálica fueron negativos. A los 20 días de vida pesó 500 g, cursó asintomático y toleró bien su fórmula, aumentando hasta los 1 700 g antes de su egreso a los 5 meses. A los 12 meses, con peso de 2.8 kg y retraso en el desarrollo psicomotor de 6 meses para la edad cronológica, no desarrolló retinopatía del prematuro, leucomalacia periventricular ni hemorragia intrancraneal.
Conclusión. Se reporta el caso de un neonato de 480 g al nacer, de 31 semanas de gestación, que presenta RCIU grave y retraso en el desarrollo psicomotor. Sin embargo, no presenta leucomacia paraventricular ni hemorragia paraventricular.
