The prognosis for neonates with abdominal cysts is generally favorable, especially if the cyst is benign and managed appropriately. Most cysts do not recur after treatment, and the risk of complications is low. However, the long-term outcome can depend on the underlying cause of the cyst and whether it is associated with other congenital anomalies or syndromes. Regular follow-up is essential to monitor the child's development and address any emerging issues.
