| Abstract |
|
Infection of hepatic cyst is a serious complication of autosomal dominant polycystic kidney disease (ADPKD). Early diagnosis of infected cyst is crucial and usually requires conventional modalities, including ultrasound and computed tomography. However, their contribution is limited because of nonspecific results. We report a case of hepatic cyst infection for which 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) scan allowed the exact localization of the infected cyst and the precise drainage procedure. A 48-year-old woman with ADPKD presented with fever and RUQ pain. Contrast enhanced computed tomography did not show any evidence of complicated or infected cysts in both kidneys and liver. Though she had been treated by antibiotics for 7 days, patient’s symptoms were not improved. However, 18F-FDG PET-CT scan revealed infected cyst in the left lobe of liver exactly. After percutaneous drainage based on 18F-FDG PET-CT imaging, the hepatic cyst infection was controlled. Therefore, 18F-FDG PET-CT imaging could be a valuable tool to identify the exact localization of cyst infection, which may contribute to drain the infected cyst. We report this case with a brief review of relevant literature. |
