Kimura Disease Simulating Hodgkin’s Lymphoma on 18F FDG PET-CT: Report of a Case

We report the case of a 16-year-old male patient presenting with several mass lesions on the left side of his neck that had been there for weeks. Whole-body (18)F-fluorodeoxyglucose positron emission tomography and computed tomography ((18)F FDG PET-CT) revealed multiple focal areas of increased uptake of fluorodeoxyglucose (FDG) on the left side of the neck, left supraclavicular fossa, left axilla, and mediastinum, simulating the imaging findings of Hodgkin's lymphoma. Subsequent incisional biopsy of lymph nodes in the left supraclavicular fossa with histologic examination confirmed the diagnosis of Kimura disease. The differential diagnoses should include Kimura disease when evaluating regional or generalized lymphadenopathy seen on (18)F FDG PET-CT because it also may show prominent uptake of FDG.
