Figure 4 (A) Initial PET-CT with evidence of widespread abnormal fluorodeoxyglucose (FDG) uptake involving multiple lymph node chains (cervical, mediastinal, abdominal), diffuse activity in the liver and spleen, pulmonary nodules, and multiple osseous lesions. No increased uptake was noted in the kidneys. (B) A repeat PET-CT at 7 months showed significant improvement of the widespread FDG-avid lesions.
