This is a hypoplasia of the pleuroperitoneal membrane. The guts herniate into the thorax, usually on the left side, and result in hypoplasia of the lungs (because they're horribly compressed).
pg32What's weird to me is that if you usually see air in the intestines on x-ray when they are in the abdomen, why is there no air in the thorax in CDH? The intestines should still have air in them, right? Also, what is filling the abdomen that causes it to appear grayed-out in CDH? +1
drzed@pg32 You can actually see a gastric bubble if you squint hard enough. Look at where the NG tube is placed; there is a radiolucency to the patient's right of the NG tube which is most likely the stomach. It probably then is radioopaque distally due to the pyloric sphincter, and air having a tendency to rise. +2
bbrAny idea what "absence of bowel gas in the abdomen" is referring to? +1
rkdangmy interpretation was absence of bowel gas in abdomen --> the bowel is not in the abdomen --> incomplete formation of pleuroperitoneal membrane
bowel gas is a normal finding that you often see on x rays of the abdomen in a normal patient+2
seba0039@rkdang is it also abnormal that you cannot see any air in the lungs? This threw me off when I was trying to read the radiograph.+
yousif7000the naso"gastric" tube is in the "thorax" that what gave it out +2
sandysandy@seba0039 pulmonary hypoplasia (poorly developed bronchial tree with abnormal histology) is associated with CDH. FA 2020 pg660+
