Biliary and Liver Abscesses Demonstrated with Tc-99m DISIDA and Ga-67 Imaging

A 76-year-old woman with fever of unknown origin had a cholecystectomy 2 months earlier. Blood and pus cultures from percutaneous transhepatic drainage showed Staphylococcus aureus. Immediately after drainage, both Tc-99m DISIDA and Ga-67 imaging were performed. Tc-99m DISIDA cholescintigraphy showed stasis of radiotracer at the dome of the right hepatic lobe and in the biliary tree. The Ga-67 scan revealed multiple focal areas of increased radiotracer accumulation in both hepatic lobes. Under both drainage and antibiotic treatment, the patient was discharged in stable condition.
