Teenager with a liver lesion

Axial and coronal CT with contrast of the abdomen arterial phase imaging (left) shows an enhancing round lesion in the dome of the liver that has a central scar which fills in on the portal venous phase imaging and becomes isodense with the surrounding liver parenchyma (center). Axial T1 MRI with Eovist (hepatocyte specific) contrast of the abdomen in the arterial phase (right upper) again shows the enhancing round lesion with a central scar that fills in the portal venous phase imaging (right center) and then retains its contrast on the delayed phase imaging (right lower).

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.

The diagnosis was ulcerative colitis.

Teenager with abdominal pain

BE of ulcerative colitis — AP spot image of the rectosigmoid colon from a barium enema shows multiple fine mucosal ulcerations.

The diagnosis was ulcerative colitis.

Teenager with poorly controlled inflammatory bowel disease

CT of Crohn's disease with fistula and abscess — Axial CT with contrast of the abdomen shows a thick-walled mass that is filled with air and oral contrast that is located medial to the oral contrast-filled thickened ascending colon and above the right psoas muscle. An extensive amount of inflammatory change is seen in the mesenteric fat in the right lower quadrant.

The diagnosis was Crohn disease with a fistula to an abscess above the right psoas muscle.

Teenager with abdominal pain

Small bowel follow through of Crohn's disease — AXR AP from a small bowel follow through shows bowel fold thickening in the proximal ileum in the left lower quadrant and bowel lumenal narrowing in the mid ileum in the midline that continues to the terminal ileum in the right lower quadrant.

The diagnosis was Crohn disease.

School ager with acute lymphblastic leukemia and abdominal pain

US of typhlitis — Transverse (above) and sagittal (below) US of the cecum show marked thickening of the wall of the cecum which is lying above the right psoas muscle.

The diagnosis was typhlitis in a patient with acute lymphocytic leukemia.

School ager with abdominal pain, diarrhea, and vomiting

AXR and CT and US of pseudomembranous colitis — AXR AP (above left) shows thickening of the haustra of the transverse colon (thumb printing). Axial CT with contrast of the abdomen (above right) shows diffuse thickening of the colon which is markedly thickened in the ascending colon compared to the descending colon. An accordion sign is demonstrated in the ascending colon. Sagittal (below left) and transverse (below right) US of the cecum show a diffusely thickened cecum.
