68Ga-FAPI-04 Detected Hepatic Arteriovenous Malformation in a Patient With IgA Nephropathy

Abstract

A 51-year-old woman with a history of IgA nephropathy was found to have a mass in the right lobe of the liver by abdominal ultrasound. The PET/CT scan revealed elevated 68Ga-FAPI-04 uptake in the aforementioned lesion, indicating the potential presence of liver cancer. However, subsequent histopathological analysis confirmed it to be an arteriovenous malformation. This case illustrates that 68Ga-FAPI-04 uptake can occur in arteriovenous malformation and is a benign cause of 68Ga-FAPI-04 uptake.
