I think the answer is C) Pulmonary hypoplasia. The infant has congenital diaphragmatic hernia (I guess the stomach and the small bowel can be seen protruding in the left hemithorax) which leads to pulmonary hypoplasia.

In my understanding, in Potter syndrome you can also find pulmonary hypoplasia, but you can not see abdominal content in the thorax and this is due to renal agenesis, which leads to olygohydramnios and no development of the lungs. And in this case, I think renal agenesis would have been the cause of death. Please correct me if I am wrong.

yes, you're true regarding the case presented here is CDH..as stomach and small bowel protruded in lt thorax(which is not seen in potter sequence)

but in potter sequence too most common cause of death is pulmonary hypoplasia..not renal agenesis...
it's renal agenesis is the cause of the potter sequence,by which fetus cant urinate ..so ultimately develop in oligohydramnios.....amniotic fluid is extremely essential for stretching of the lung airways in fetus...so develops into pulmonary hypoplasia....
so immediately after birth baby cant breath properly which ultimately lead to death most of the times........
hope it helps..thanks

Default Agreed

I would have to agree C pulmonary hypoplasia.
In the right upper corner of the image (baby's left mediatinum) you can see an air fluid level meaning gastrointestinal contents are in the mediastinum. With GIT in thorax the lungs cannot fully develop.

The correct answer is C. Pulmonary hypoplasia is the most common cause of death in infants born with congenital diaphragmatic hernia. When the pleuroperitoneal folds fail to fuse with the other components of the diaphragm during development, a hole is created that allows bowel into the thorax. The physical compression of the bowels on the lung buds then prevents full development of the respiratory system (pulmonary hypoplasia). This leads to a common presentation of dyspnea and cyanosis and, unless it can be repaired surgically, eventually leads to death.

Answer A is incorrect. Cardiac tamponade is most frequently associated with a pericardial effusion. This is not a common complication of congenital diaphragmatic hernia.

Answer B is incorrect. Mediastinal shift does occur in congenital diaphragmatic hernia, as the bowel invades the thorax and pushes the mediastinum to the right. However, this in itself is not a cause of death.

Answer D is incorrect. Renal agenesis is not associated with congenital diaphragmatic hernia.

Answer E is incorrect. Although it is theoretically possible for a volvulus to develop as the bowel herniates into the thorax, small bowel obstruction is not a common complication of congenital diaphragmatic hernia.
