Example of the use of (¹⁸F)FDG PET/CT in a patient with non-Hodgkin’s lymphoma and sudden onset of fever and a positive blood culture for Streptococcus dysgalactiae. The patient underwent TTE and TEE, which were negative. Antimicrobial treatment was started. Due to the lack of clinical response, the patient underwent (¹⁸F)FDG PET/CT, which revealed infection, as indicated by the black and yellow arrows, involving the pocket of the device ((A), from left to right, CT, PET, and superimposed PET/CT transaxial (upper panel) and coronal (lower panel and (B) non-attenuated corrected transaxial images) as well as the intracardiac portion of the lead extending to the tricuspid valve ((C), from left to right, noncontrast CT, PET, and fused PET/CT coronal images). Based to the PET/CT findings, the device was extracted and replaced.
