18F-FDG PET/CT diagnosis of liver cyst infection in a patient with autosomal dominant polycystic kidney disease and fever of unknown origin

The diagnosis, localization and treatment of infected cysts in the kidney or liver of patients with autosomal dominant polycystic kidney disease (ADPKD) remain a clinical challenge. We report the findings of (18)F-FDG PET-CT in an ADPKD diagnosed patient who required renal transplantation five years...

Summary:The diagnosis, localization and treatment of infected cysts in the kidney or liver of patients with autosomal dominant polycystic kidney disease (ADPKD) remain a clinical challenge. We report the findings of (18)F-FDG PET-CT in an ADPKD diagnosed patient who required renal transplantation five years before and in his follow up presented repeated episodes of bacteriemia without known focus on radiological tests performed. The (18)F-FDG PET-CT scan showed numerous hypermetabolic images with focal or ring-shaped morphology related to the content and the wall of some hepatic cysts. The increased metabolic activity was localized on segments VI and VII. We proceeded to drainage of one cyst in segment VI, removing 110 cc of purulent fluid which grew E. Coli BLEE. The (18)F-FDG PET/CT scan should be included in the diagnostic algorithm for detecting infected liver cysts in patients with ADPKD and fever of unknown origin.
