Abstract

An 18-year-old woman with intermittent fever, pancytopenia, abnormal liver function, and enlarged lymph nodes and hepatosplenomegaly was clinically suspected as hemophagocytic lymphohistiocytosis. 18 F-FDG PET/CT showed increased metabolism in multiple lymph nodes, which were highly suggestive of lymphoma. No increased CXCR4 expression in lymph nodes was demonstrated on 68 Ga-pentixafor PET/CT. Subsequent right neck lymph node biopsy pathology revealed EBV-associated lymphoproliferative disorders. Our case shows that 68 Ga-pentixafor PET/CT may have potential value in differentiating EBV-associated lymphoproliferative disorders from lymphomas.
