Lymphadenopathy Due to Kimura’s Disease Mimicking Lymphoma on FDG PET/CT

Kimura's disease is a clinically rare, chronic, benign lymphoproliferative disorder of unknown etiology. A 36-year-old man presented with painless axillary swelling, which was suspected as lymphoma. PET/CT was performed for staging. The images showed multiple foci of increased activity in bilateral axillary and right inguinal lymph nodes. Laboratory tests revealed an increased eosinophil ratio and eosinophil count. Pathological examination from dissected axillary lymph nodes was consistent with Kimura's disease.
