Newborn who is having difficulty handling their secretions

CXR of esophageal atresia without tracheo-esophageal fistula
CXR AP (above left) shows the chest to be unremarkable aside from a right sided aortic arch. However, there is no air seen within the gastrointestinal tract. CXR lateral (above right) shows the proximal esophagus behind the trachea to be very dilated. CXR obtained after placement of a nasogastric tube (below) shows the nasogastric tube to be looped within the proximal esophagus.

The diagnosis was esophageal atresia without tracheo-esophageal fistula.

Infant with bilious vomiting

Upper GI of malrotation with midgut volvulus
AP image from an upper GI exam shows the contrast filled stomach in the upper right of the image emptying into the duodenal bulb which is just to the right of the spine. The position of the duodenal-jejunal junction is not well defined and it may be in the right upper quadrant or in the left upper quadrant. In either case, it is well below the level of the duodenal bulb and therefore is malpositioned.

The diagnosis was malrotation with midgut volvulus.

Young adult with a gastrojejunostomy tube and chronic abdominal pain

CT of gastrojejunostomy tube causing duodenal-jejunal intussusception
Axial (above) CT with contrast of the abdomen shows a round soft tissue mass to the right of the vertebral body that has a target sign appearance and that has a jejunostomy tube coursing in the center of it. Coronal CT (below) shows the soft tissue mass to be long in length and to comprise the second and third parts of the duodenum and the proximal jejunum and to have the jejunostomy tube coursing throughout its length.

The diagnosis was gastrojejunostomy tube malfunction due to the formation of a duodenal-jejunal intussuception forming around the tip of the jejunostomy tube.

Preschooler with abdominal pain who yesterday was playing with a construction toy that utilizes rare earth magnets

AXR of rare earth magnets causing small bowel obstruction
AXR shows multiple round and cylindrical radiopaque objects in the lower abdomen that are all in close approximation to each other. There are multiple dilated loops of small bowel present.

The diagnosis was gastrointestinal foreign bodies in the form of 9 rare earth magnets which had stuck together in the small bowel causing small bowel obstruction and resulting several days later in small bowel necrosis and small bowel perforation.

School ager who started coughing after eating peanuts

CXR of peanut in left mainstem bronchus
Inspiratory CXR AP (left) is normal and shows the lungs to be clear and to be symmetrically aerated and no radiopaque foreign body is seen. Expiratory CXR AP (right) shows a normal decrease in the volume in the right lung in expiration while there is no decrease in the volume in the left lung in expiration (air trapping) and there is mediastinal shift to the right.

The diagnosis was airway foreign body in the form of a peanut in the left mainstem bronchus.
