A 1.5 month old male infant presented with jaundice, abdominal distension, and fever. Liver function tests showed acute liver failure. Initial infections were ruled out. Urine tests found high galactose levels and low galactose-1-phosphate uridyl transferase enzyme activity, diagnosing galactosemia as the cause of acute liver failure. Despite treatment, the infant's condition deteriorated and he succumbed to complications on the ninth day of admission.
