Burkitt Lymphoma Involving Multiple Rare Extralymphatic Sites Uncovered in an FDG PET/CT

Burkitt lymphoma is an aggressive mature B-cell lymphoma. Burkitt lymphoma is known to present with involvement of multiple nodal and extranodal sites. Extranodal involvement commonly occurs in the abdominal cavity, in the form of bowel obstruction, intussusception, and/or omental, mesenteric deposits. Here, we present a case of Burkitt lymphoma where 18 F fludeoxyglucose positron emission tomography/computed tomography was performed for staging and treatment response assessment. We demonstrate a rare presentation of involvement of multiple extranodal sites of lymphoma in a single patient, including rare organs, namely the gallbladder and kidneys.
