Official Title: Use of Fluorodeoxyglucose Positron Emission Tomography With Computed Tomography for the Evaluation of Autoimmune Lymphoproliferative Syndrome Lymphadenopathy Suggestive of

Brief Summary:

Background:

- Autoimmune lymphoproliferative syndrome (ALPS) is a genetic disorder of the lymph system. People with ALPS often have swollen lymph nodes, especially in the neck and armpit. They also have a much higher risk of developing lymphoma. It is not always easy to determine whether the swollen lymph nodes are caused by ALPS or by lymphoma. Researchers want to see whether different imaging studies can show the difference between ALPS and lymphoma. The studies used will be positron emission tomography (PET) and computed tomography (CT). Researchers will use a drug called fluorodeoxyglucose (FDG) to look at the lymph nodes.

Objectives:

- To see how well imaging studies can distinguish between swollen lymph nodes caused by ALPS or by lymphoma.

Eligibility:

  • Individuals must be 5 years of age or older and enrolled on the National Institutes of Health natural history study of ALPS.
  • Participants should either have lymphoma or have symptoms that suggest possible lymphoma.

Design:

  • Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected.
  • Participants will have an FDG-PET/CT scan. It will be performed according to standard procedures.
  • If the results of the scan do not show lymphoma, participants will stay on the study for 1 year for clinical follow up. They may have a second FDG-PET/CT scan if there is a change in symptoms. Such changes include further e
