The diagnosis was ileocolic intussusception.

Infant with coughing and gagging when feeding

Upper GI of tracheal aspiration — Lateral image from an upper GI shows barium in the trachea anteriorly as well as in the pharynx and esophagus posteriorly.

Ultrapremature newborn with massive abdominal distension who has passed only a little meconium after 4 days

Enema of meconium obstruction of prematurity — AXR AP (above) shows massively dilated loops of bowel throughout the entire abdomen. AXR AP taken at the beginning of an enema performed with water-soluble contrast (lower left) shows meconium filling almost the entire colon. AXR AP taken later in the exam (lower right) shows reflux of contrast into massively dilated loops of small bowel. Several hours after the enema, the patient passed a large amount of meconium and the abdomen became completely decompressed.

Infant with an abdominal mass

MRI of inflammatory myofibroblastic tumor — Coronal T1 MRI without (upper left) and with (upper right) contrast of the abdomen shows a large well circumscribed bi-lobed solid mass that enhances homogeneously in the abdomen and that along with the axial T2 image (below) is shown to not arise from any of the solid organs of the abdomen.

School ager with retching

CXR and upper GI of hiatal hernia — CXR AP shows an air fluid level at the level of the diaphragm. Lateral spot image from an upper GI shows the fundus of the stomach sliding through the esophageal hiatus into the chest.

The diagnosis was hiatal hernia.

Preschooler with a purpuric skin rash and abdominal pain

Small bowel follow through of Henoch-Schonlein purpura — AXR AP (left) and spot image of the terminal ileum (right) from a small bowel follow through show bowel wall fold thickening (thumbprinting) throughout the jejunum and ileum.

The diagnosis was Henoch-Schonlein purpura.

Preschooler with reflux

Upper GI of esophagitis and esophageal stricture from gastroesophageal reflux — Lateral spot image from an upper GI shows multiple small ulcerations in the esophageal mucosa and a fixed tight narrowing of the distal esophagus in the middle of the image which never opened up during the exam. Gastroesohageal reflux was also demonstrated throughout the exam

The diagnosis was a distal esophageal stricture due to esophagitis from gastroesophageal reflux.

Teenager with a liver lesion

The diagnosis was focal nodular hyperplasia.

School ager with abdominal pain

AXR of constipation — AXR AP shows a marked amount of stool in the ascending colon that decreases somewhat in the transverse and descending colon but that massively distends the rectum to fill almost the entire pelvis.

The diagnosis was constipation.

Preschooler with abdominal pain

AXR and small bowel follow through of ascariasis — AXR AP (left) shows numerous round soft tissue densities projecting throughout the small bowel centrally located within the abdomen. AXR AP from a small bowel follow through (right) shows numerous linear tubular filling defects within the small bowel.

The diagnosis was ascariasis.

School ager with vomiting when eating

CXR and upper GI of achalasia — CXR PA and lateral (above) shows a dilated esophagus with an air-fluid level within it. AP and lateral images from an upper GI (below) show an extremely dilated esophagus with fluid-fluid level within it that terminates in a beak at the gastroesophageal junction.

The diagnosis was achalasia.

Teenager with bloody diarrhea

Enema of pseudopolyps in ulcerative colitis — AP AXR (left) and magnified AP spot image of the splenic flexure (right) from a double contrast barium enema shows a large number of small polypoid lesions throughout the colon with the space between the polyps appearing to be denuded and ulcerated.

The diagnosis was pseduopolyps in a patient with ulcerative colitis.

Teenager with abnormal pigmentation around the mouth

Small bowel follow through of Peutz-Jeghers syndrome — AP (left) and lateral (right) spot images from an upper GI show several round filling defects in the proximal jejunum, the most notable being in the left-most aspect of the AP image.

The diagnosis was a hamartomatous polyp in a patient with Peutz-Jeghers syndrome.

School ager with rectal bleeding

Small bowel follow through of juvenile polyp — Spot image of the jejunum from a small bowel follow through shows a polypoid filling defect in the center of the bowel lumen whose stalk attaches to the bowel mucosa.

The diagnosis was juvenile polyp.

Teenager with rectal bleeding

Enema of familial adenomatous polyposis — AP spot image of the hepatic flexure of the colon from a double contrast barium enema shows contrast coating multiple polypoid lesions which arise from the mucosal surface of the colon and extend into the colonic lumen.

The diagnosis was adenomatous polyps in a patient with familial adenomatous polyposis.

Teenager with abdominal pain

BE of ulcerative colitis — AXR AP from a barium enema (left) shows the loss of haustral markings in the colon (lead pipe sign). The magnified view (right) suggests the presence of multiple fine mucosal ulcerations.
