Inguinal lymphadenopathy of cat-scratch disease mimicking malignant hemopathy on 18FDG-PET/CT

Abstract 18-Fluorodeoxyglucose positron emission tomography/computed tomography ( 18 FDG-PET/CT) is a valuable imaging technique for the diagnosis and staging of malignant pathologies. Nevertheless, false positive exams exist, especially in the case of infectious or inflammatory diseases. We report a case of a 39-year-old man who presented a cat-scratch disease (CSD), which was revealed through hypermetabolic inguinal lymphadenopathy on 18 FDG-PET/CT mimicking malignant hemopathy. Finally, biopsy and PCR analysis revealed Bartonella henselae infection.
