title: FDG PET/CT detection of intussusception caused by lymphoma in a pediatric patient.
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.
