School ager with abdominal pain

CT of Meckel's diverticulum causing small bowel obstructin
Axial (above), coronal (lower left) and sagittal (lower right) CT with contrast of the abdomen shows multiple dilated loops of small bowel and a soft tissue mass in the right upper quadrant just beneath the gall bladder that shows the target sign on the sagittal image and the pseudokidney sign on the transverse and coronal images. The soft tissue mass was still present on an US performed 1 hour later.

The diagnosis was small bowel obstruction due to an ileal-ileal intussusception caused by Burkitt lymphoma.
