A 15-day- old male infant presented with features suggestive of congenital adrenal hyperplasia (CAH). But on detailed investigation, he had normal 17-OH Progesterone and high aldosterone levels. Infant also had right sided hydronephrosis and associated urinary tract infection. Hence, a diagnosis of secondary pseudohypoaldosteronism was made. There was good response to sodium chloride supplementation and he was thriving well on follow up. While evaluating any infant with suspected CAH, one should consider secondary pseudohypoaldosteronism, especially when risk factors like urinary tract obstruction or UTI coexists.
