Elevated ¹⁸F-AIF-FAPI-04 Uptake in Hepatic Hemangioma

A 67-year-old woman who was diagnosed with intrahepatic cholangiocellular carcinoma (CCC) by biopsy underwent F-18-FDG and F-18-AIF-FAPI-04 PET/CT for initial and treatment assessment. In addition to CCC, she had a history of hepatic hemangioma for 3 years. F-18-FDG PET/CT images showed increased uptake in CCC, but no uptake in hemangiomas. However, images on F-18-AIF-FAPI-04 PET/CT indicated negative F-18-AIF-FAPI-04 uptake in CCC, but intense activity in hemangiomas. Our case illustrates that hepatic hemangioma demonstrated intense F-18-AIF-FAPI-04 uptake, and final diagnosis should be made with caution.
