Pseudohypoaldosteronism (PHA) in infants is manifested by presence of hyperkalemia, hyponatremia, and metabolic acidosis. At initial stages, PAH is generally suspected as congenital adrenal hyperplasia. Transient PHA has been reported in infants with urinary tract infection and urinary tract malformation. We report a case of 5-month-old infant with failure to thrive and finally diagnosed with transient PHA due to urinary tract infection with vesicoureteral reflux.
