ABSTRACT
RESUMEN El complejo de esclerosis tuberosa es una afección genética, aproximadamente dos tercios de los casos ocurren esporádicamente; se caracteriza por lesiones y tumores benignos (hamartomas) en múltiples sistemas orgánicos. La detección prenatal precisa es importante para el pronóstico, una decisión sobre el resultado del embarazo y el asesoramiento. Se reporta el caso de una gestante sana y su feto con diagnóstico presuntivo de esclerosis tuberosa, por hallazgo de masas intracardiacas en ecografía prenatal, confirmados luego del nacimiento, con afectación de otros órganos, cumpliendo con criterios mayores de diagnóstico. El caso presentado es el primero registrado en el Departamento de Neonatología y tiene el objetivo de mostrar la aproximación diagnóstica prenatal y postnatal de una enfermedad relativamente rara.
ABSTRACT Tuberous sclerosis complex is a genetic condition caused by mutations in the tumor suppressor genes TSC1 and TSC2, located on chromosomes 9 and 16 respectively. Approximately two-thirds of cases occur sporadically and the overall incidence has been estimated to be 1 in 5,800 live births. It is characterized by benign lesions and tumors (hamartomas) in multiple organ systems (brain, heart, skin, eyes, kidneys, lungs, liver). Accurate prenatal detection is important for prognosis, a decision about the pregnancy outcome, and counseling. We report the case of a healthy pregnant woman and her fetus with a presumptive diagnosis of tuberous sclerosis, due to the finding of intracardiac masses on prenatal ultrasound, confirmed after birth, with involvement of other organs, fulfilling the major diagnostic criteria. The case presented is the first recorded case at our Department of Neonatology and this report illustrates the prenatal and postnatal diagnostic approach of a relatively rare disease.
