FDG accumulation in the gallbladder has been reported as an indication of either malignancy or inflammation. We here report a case of FDG accumulation in the gallbladder without pathology in the gallbladder. A 15-year-old girl with Hodgkin disease underwent staging FDG PET/CT, which revealed not only the abnormal activity in the lymph nodes and left ilium, which were consistent with the malignant involvement, but also increased activity in the gallbladder. The patient had no symptoms related to hepatobiliary system at the time of scan and did not suffer any problem related to hepatobiliary system during 14 months of follow-up.
