Severe electrolyte imbalances and nonspecific symptoms in an infant

The pediatric patient was admitted to the hospital on several occasions with feeding difficulties, vomiting, severe dehydration, and electrolyte imbalances. During his second hospitalization, he was in critical condition. The endocrinological evaluations subsequently initiated revealed that he was suffering from secondary pseudohypoaldosteronism (PHA). This case report illustrates that PHA should also be considered in infants with known urinary tract anomalies and unexplained electrolyte imbalances.
