Diagnostic Considerations
Imaging studies help to develop your differential diagnosis.
Fetal ultrasound may be the first indication that a cystic lesion is present. Chest films can provide a presumptive diagnosis based on the location of the lesion.
Contrast medium enhanced CT can define calcifications and is generally considered superior to MRI, unless there are concerns about additional anomalies.
