What is the recommended schedule for abdominal ultrasound in patients with Beckwith-Wiedemann syndrome during childhood?

The recommended schedule for abdominal ultrasound in patients with Beckwith-Wiedemann syndrome focuses on monitoring for the development of abdominal tumors, particularly Wilms tumor and hepatoblastoma, which are more prevalent in this population. The correct choice indicates that abdominal ultrasounds should be performed every 3 months until the age of 4 and then annually until the age of 8.

This approach balances the need for early detection of potential tumors, as the risk is highest during early childhood. The frequency of every 3 months until age 4 allows for close surveillance during this critical period when the likelihood of tumor development is heightened. Following this, annual ultrasounds until age 8 provide continued monitoring as the risk may still be significant, though it diminishes gradually after early childhood.

This proactive surveillance helps ensure any tumors can be identified and treated at the earliest possible stage, maximizing the chances of positive outcomes for affected children.
