Primary Epstein-Barr virus infection diffusing F18- fluorodeoxyglucose-positron emission tomography/computed tomography response monitoring of Hodgkin's disease: A case report

Introduction. Hodgkin's disease is highly curable by radiotherapy and/or chemotherapy, but refractory disease or early relapses are rarely cured by conventional salvage therapy. Case presentation. We report a case of a 20-year-old Caucasian man, with a biopsy-proven intrapulmonary relapse of Hodgkin's disease, for whom salvage chemotherapy was administered. During salvage chemotherapy intense increased F18-fluorodeoxyglucose uptake was noticed in multiple lymph nodes and diffuse increased splenic uptake, suggesting chemotherapy-refractory disease. However, additional information obtained from the patient revealed he recently had met his first girlfriend. An asymptomatic primary Epstein-Barr virus infection was considered proven. Conclusions: Interim F18-fluorodeoxyglucose-positron emission tomography/computed tomography is a strong prognostic factor for advanced Hodgkin's and may better identify those patients needing intensified chemotherapy. Related to the nonspecificity of F18- fluorodeoxyglucose, clinical awareness of the potential interference of intercurrent asymptomatic viral infections with treatment and remission status monitoring continues to be important in the interpretation of equivocal medical imaging results. © 2014 Balink and Hoogendoorn; licensee BioMed Central Ltd.
