A 70-year-old man with a history of autosomal dominant polycystic kidney disease was referred for 18F-FDG PET/CT scans twice at 6-month intervals due to repeated fever with negative conventional imaging studies. The FDG PET/CT scans revealed different hepatic cyst lesions in the 2 scans, with a large infected cyst in the second study. After aspiration and intravenous antibiotics treatment, the patient was discharged and remained uneventful thereafter for 6 months.
