The Bochdalek hernia, also known as a postero-lateral diaphragmatic hernia, is the most common manifestation of CDH, accounting for more than 95% of cases. In this instance the diaphragm abnormality is characterized by a hole in the postero-lateral corner of the diaphragm which allows passage of the abdominal viscera into the chest cavity.
Bochdalek hernia is one of two forms of a congenital diaphragmatic hernia, the other form being Morgagni hernia.A Bochdalek hernia is a congenital abnormality in which an opening exists in the infant's diaphragm, allowing normally intra-abdominal organs (particularly the stomach and intestines) to enter into the thoracic cavity.
Causes of pulmonary hypoplasia include a wide variety of congenital malformations and other conditions in which pulmonary hypoplasia is a complication. [1] These include congenital diaphragmatic hernia, congenital cystic adenomatoid malformation, fetal hydronephrosis, caudal regression syndrome, mediastinal tumor, and sacrococcygeal teratoma with a large component inside the fetus.
A congenital diaphragmatic hernia is a distinct problem, occurring in up to 1 in 2000 births, and requiring pediatric surgery. Intestinal organs may herniate through several parts of the diaphragm , posterolateral (in Bochdalek's triangle (lumbocostal triangle), resulting in a Bochdalek hernia ), or anteromedial-retrosternal (in the cleft of ...

Fetal conditions can also cause a mediastinal shift during development. For example, pulmonary hypoplasia is the underdevelopment of a lung due to various etiologies. These include agenesis due to gene mutation, fetal hydrothorax, and congenital diaphragmatic hernia. These conditions lead to incomplete development of lung tissue or hypoplasia.
A hiatus hernia is a hernia in which parts of the lower esophagus or stomach that are normally in the abdomen pass abnormally through the diaphragm and are present in the thorax. Hernias are described as rolling , in which the hernia is beside the oesophagus, or sliding , in which the hernia directly involves the esophagus.
