Heterogeneous bone marrow uptake on interim 18F-fluorodeoxyglucose positron emission tomography for lymphoma mimicking disease progression: a case report

Introduction The use of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) scanning for baseline staging and assessment of treatment response for higher grade lymphomas is considered to be the standard of care. Evaluation of lymphomatous bone marrow infiltration on 18F-FDG PET can usually distinguish between normal regenerating marrow following chemotherapy by a characteristic pattern of uptake.
