title: FDG PET/CT images demonstrating epididymo-orchitis in a patient with HIV, acute kidney injury and known epididymo-orchitis on scrotal ultrasound.
abstract: A 52-year-old man with HIV was referred for an F-FDG PET/CT scan for the cause of kidney injury. FDG PET/CT scan revealed increased renal cortical FDG activity, which can be seen in HIV nephropathy or acute interstitial nephritis. Diffuse increased FDG uptake was demonstrated within the right testicle and epididymis, consistent with the patient's known right epididymo-orchitis, as diagnosed on ultrasound 1 week before admission. Multiple enlarged lymph nodes with increased FDG activity were also found within the right inguinal and external iliac nodal chains, which were presumed to be reactive. The patient was treated with ciprofloxacin with symptomatic improvement.
