At what age do choledochal cysts typically present?

Choledochal cysts usually present in the first year of life and are more commonly diagnosed in infants and young children. These cysts are congenital anomalies that can cause obstructive jaundice and other gastrointestinal symptoms shortly after birth or within the first few months of life.

The reason the first year of life is significant is that symptoms such as abdominal pain, jaundice, and biliary colic may emerge as the child grows, often prompting imaging studies and leading to diagnosis. Early recognition is crucial to prevent complications such as pancreatitis, cholangitis, or malignancy.

While choledochal cysts can theoretically be detected at birth, the symptoms may not always be apparent immediately, making the first year of life the typical presentation window. Late diagnosis can occur, but most cases are identified before the child reaches early childhood or adolescence.
