Causa infrecuente de hipertensión arterial en lactantes: neuroblastoma congénito quístico suprarrenal. Caso clínico

The frequency of hypertension (HBP) in children has increased significantly over the past decade. The younger the patient the greater the likelihood of having secondary HBP. Thus, the main causes of hypertension in new-borns are of renovascular or parenchymatous origin. objective: To present the case of an infant with hypertension caused by a congenital cystic neuroblastoma (NB). Case History: Newborn with prenatal diagnosis of adrenal cyst, who evolved with significant hypertension unresponsive to medical therapy. Neuroblastoma was suspected on the basis of magnetic resonance imaging findings and resection of the lesion was able to resolve the hypertension and to confirm the diagnosis by anatomo-pathological study. Conclusion: Most cases of neonatal hypertension are of renal origin, with the 2 largest categories being renovascular and renal parenchymal diseases. NB is the most common neonatal malignancy. It usually presents as an abdominal mass of antenatal diagnosis, being the hypertension an unusual form of presentation. La frecuencia de hipertension arterial (HTA) en ninos ha aumentado significativamente en la ultima decada. A menor edad del paciente mayor es la probabilidad de que la HTA sea secundaria. Asi, las principales causas de HTA en recien nacidos son de origen renovascular o parenquimatoso. objetivo: Presentar el caso de un lactante hipertenso por neuroblastoma (NB) congenito quistico. Caso Clinico: Recien nacido con diagnostico prenatal de quiste suprarrenal, quien evoluciono con HTA por sobre el percentil 99 para edad, sexo y talla, sin respuesta a terapia farmacologica. La resonancia magnetica permitio realizar el diagnostico presuntivo de neuroblastoma congenito y la reseccion de la lesion permitio resolver la HTA y confirmar el diagnostico. Conclusion: La HTA en recien nacidos generalmente se debe a causas secundarias. El NB es el tumor maligno neonatal mas frecuente que se puede presentar como una masa abdominal de diagnostico antenatal, siendo la HTA una forma infrecuente de presentacion.
