Infant with respiratory distress after begin re-intubated

CXR of endotracheal tube in the right mainstem bronchus and after it is pulled back
CXR AP (above) shows an endotracheal tube with its tip projecting deep within the right mainstem bronchus. There is complete atelectasis of the left lung with no mediastinal shift. CXR AP (below) was obtained after the endotracheal tube tip had been pulled back to an appropriate position just above the carina with subsequent near-complete re-expansion of the left lung.

The diagnosis was an endotracheal tube positioned too deep in the right mainstem bronchus.

Newborn with respiratory distress

CXR of endotracheal tube in the right mainstem bronchus and after it is pulled back
CXR AP (above) shows an endotracheal tube with its tip projecting deep within the right mainstem bronchus. There is complete atelectasis of the left lung with mediastinal shift to the left. CXR AP (below) was obtained after the endotracheal tube tip had been pulled back to an appropriate position between the clavicles and the carina with subsequent complete re-expansion of the left lung.

The diagnosis was an endotracheal tube positioned too deep in the right mainstem bronchus.

Newborn with a defect of the lower abdominal wall

AXR of cloacal exstrophy
AXR AP shows diastasis of the symphysis pubis and multiple spinal segmentation defects while the AXR lateral shows a small amount of bowel herniated anterior to the abdomen and inferior to the umbilicus along with a large skin covered spinal dysraphism posteriorly and a radioopaque marker being held in place over where the anus should be.

The diagnosis was cloacal exstrophy with bladder exstrophy, anorectal malformation and spinal segmentation anomalies.

Preschooler with superior mesenteric artery syndrome who had a feeding tube placed into the third part of the duodenum 1 day ago that is now not working. AXR (not available) showed the tip had migrated into the right upper quadrant of the abdomen

US of feeding tube tip in main portal vein
Transverse US of the liver shows the echogenic tip of a feeding tube to be in the main portal vein in the center of the image. Note the posterior shadowing from the tip extending inferiorly from it.

The diagnosis was feeding tube malfunction due to migration of the feeding tube tip out of the duodenum into the main portal vein. In the operating room the feeding tube was seen to have eroded into the superior mesenteric vein and then into the main portal vein and it was removed without complication.
