Cat scratch disease (CSD) is a rare zoonotic infection disease, and the imaging performance for evaluation varies. We present FDG PET/CT images of two cases of CSD. In one case, images showed typical findings of regional lymph node enlargement. In another case, images showed atypical findings of extensive superficial and deep lymph node enlargement.
