Fetal lung cysts that are small in size and not associated with other malformations are usually not serious and can be treated with minimally invasive surgery after the birth of the fetus; if the cysts are large or associated with other malformations, they are serious and may result in the death of the fetus and require termination of the pregnancy.
Fetal lung cysts are usually caused by congenital dysplasia, and may also be caused by fetal lung infection, which is a benign lesion.
If the fetal lung cyst is relatively small and there are no other fetal abnormalities on ultrasound, it is usually not serious and the pregnancy can continue. Regular review should be done to monitor the growth of the cyst. If the cyst is considered to be associated with a lung infection, the pregnant woman can take oral medications such as amoxicillin and ceftazidime to inhibit the growth of the cyst, or wait until the fetus is born to be treated through minimally invasive surgery.
Fetal lung cysts with other malformations are usually more serious and have a poor prognosis. In addition, fetal lung cysts that are relatively large in size will cause some compression of the surrounding area, affecting the function of other organs, and can easily lead to the death of the fetus, requiring termination of the pregnancy if necessary.
Fetal lung cysts are detected and can be followed up regularly. Pregnant women should pay attention to rest, avoid exertion and maintain a good mood during pregnancy.
