**Core Concept**
Bochdalek hernia is a type of congenital diaphragmatic hernia (CDH) resulting from a defect in the posterolateral aspect of the diaphragm. This defect allows abdominal organs to herniate into the thoracic cavity, which can compromise lung development and lead to respiratory distress.

**Why the Correct Answer is Right**
Bochdalek hernias typically occur on the left side, as the diaphragm is less muscular and more fibrous on this side, making it more susceptible to defects during embryonic development. The hernia usually involves the stomach, small intestine, and occasionally the spleen or liver. The presence of a Bochdalek hernia can lead to pulmonary hypoplasia and hypoxia due to the compression of the developing lung tissue.

**Why Each Wrong Option is Incorrect**
**Option A:** Bochdalek hernias can occur on either side of the diaphragm, but they are more common on the left side.
**Option B:** While Bochdalek hernias can be associated with other congenital anomalies, they are not typically associated with abdominal wall defects like omphalocele.
**Option C:** Bochdalek hernias are not usually diagnosed prenatally due to overlapping bowel gas in the abdomen, but they can be suspected based on the presence of polyhydramnios and an abnormal mediastinal shift.

**Clinical Pearl / High-Yield Fact**
Bochdalek hernias are a classic example of a congenital diaphragmatic hernia, and their diagnosis is often delayed until after birth due to the lack of specific prenatal markers.
