Congenital pulmonary airway malformation in a fetus, ultrasound at 19 weeks - transverse. Stomach on left image; heart on right image: displaced to right by cystic mass. The earliest point at which a CPAM can be detected is by prenatal ultrasound. The classic description is of an echogenic lung mass that gradually disappears over subsequent ...
Alveolar capillary dysplasia (ACD) is a rare, congenital diffuse lung disease characterized by abnormal blood vessels in the lungs that cause highly elevated pulmonary blood pressure and an inability to effectively oxygenate and remove carbon dioxide from the blood.
The increased fluid in the lungs leads to increased airway resistance and reduced lung compliance. It is thought this could be from lower levels of circulating catecholamines after a caesarean section, which are believed to be necessary to alter the function of the ENaC channel to absorb excess fluid from the lungs. Pulmonary immaturity has ...
Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.

The new system offers a better description of underlying pulmonary disease and its severity. [5] "The term 'bronchopulmonary dysplasia' was first used by [William] Northway et al. in 1967 to describe a chronic form of injury to the lungs caused by barotrauma and oxygen injury in preterm infants requiring mechanical ventilation."

PPHN can range from mild to severe disease. In the most severe form, infants experience severe hypoxemia resulting in cardiac and pulmonary complications. [4] As a result of low oxygen levels, infants with PPHN are at an increased risk of developing complications, such as asphyxia, chronic lung disease, neurodevelopment issues, and death.
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes Q30-Q34 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category.
There is no cause for most cases of neuroendocrine hyperplasia. However, a known cause is a rapid increase of pulmonary endocrine cells in the lungs in children under the age of 2 years. An increase in pulmonary endocrine cells is usually seen in adults with a history of smoking, COPD, or cystic fibrosis.
