In congenital diaphragmatic hernia all are seen except?
**Core Concept**
Congenital diaphragmatic hernia (CDH) is a condition characterized by a developmental defect in the diaphragm, allowing abdominal organs to herniate into the thoracic cavity. This can lead to respiratory distress, pulmonary hypertension, and other complications.
**Why the Correct Answer is Right**
In CDH, the herniated abdominal contents can compress and distort the developing lungs, leading to pulmonary hypoplasia (underdevelopment) and pulmonary hypertension. The herniated organs can also cause a mass effect, further compromising lung growth and function. The affected infants often present with respiratory distress, which can be severe and life-threatening.
**Why Each Wrong Option is Incorrect**
**Option A:** Bochdalek hernia is actually a type of congenital diaphragmatic hernia, characterized by a posterolateral defect in the diaphragm.
**Option B:** Morgagni hernia is another type of congenital diaphragmatic hernia, typically located in the anterior (front) part of the diaphragm.
**Option C:** Hiatus hernia is a type of congenital diaphragmatic hernia, characterized by a defect in the esophageal hiatus (opening) of the diaphragm.
**Clinical Pearl / High-Yield Fact**
It's essential to note that CDH is often associated with other congenital anomalies, such as cardiac defects, chromosomal abnormalities, and gastrointestinal malformations. A thorough evaluation and workup are crucial in the diagnosis and management of CDH.
**Correct Answer:** A.
