Abstract:
A previously healthy 9-year-old boy presented to an outside hospital with a history of abdominal pain and vomiting. An abdominal x-ray was unremarkable. A CT of the abdomen and pelvis performed to evaluate possible obstruction after weight loss and vomiting over a 3-week period demonstrated a large retroperitoneal mass. Laparoscopic biopsy showed diffuse large B-cell lymphoma. FDG PET/CT was performed for staging. An ileocolic intussusception was identified on the PET/CT. The intussusception was successfully managed with medical treatment. We present FDG PET/CT findings in intussusception with non-Hodgkin lymphoma as the lead point in a pediatric patient.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
