Coincidence of congenital toxoplasmosis and biliary atresia in an infant.

A 4-week-old infant presenting with neonatal cholestasis was found to have congenital toxoplasmosis and biliary atresia. This is the first patient in which their coincidence is reported. Because biliary atresia can coexist with either congenital infection or inborn errors of metabolism, evaluation for an obstructive etiology of jaundice in infants with a recognized cause of intrahepatic cholestasis is necessary.
