Congenital lung diseases include bronchogenic cysts, congenital cystic adenomatoid malformations, lobar emphysema and pulmonary sequestrations, according to Children's Health. Doctors diagnose about 10 percent of congenital lung diseases when a child is born; another 14 percent are diagnosed by the age of 15.
Symptoms of congenital lung disease may include pain or difficulty with breathing, shortness of breath and wheezing, as Seattle Children's Hospital describes. Pneumonia that doesn't clear up quickly or that recurs frequently may also be a sign of congenital lung disease. A child who is experiencing difficulty breathing or recurrent pneumonia should be taken to see a doctor right away, advises Children's Health.
Bronchogenic cysts and congenital cystic adenomatoid malformations may be diagnosed based on prenatal ultrasounds, according to Children's Health. Lobar emphysema can be diagnosed with a chest X-ray after the baby is born. Pulmonary sequestrations are more likely to be diagnosed later in the child's life, generally when a doctor is examining the child for other conditions.
