Primary Solitary Tuberculosis in the Hepatic Round Ligament Detected by Ga-68-FAPI PET/CT

A 45-year-old woman recently complained of abdominal pain, poor appetite, and weight loss. Her serum ferritin, CA199, and CA242 levels were elevated. Ga-68-FAPI PET/CT revealed a subcapsular mass in the liver, which showed a significant FAPI uptake without other abnormal activity. Postoperative pathological examination confirmed tuberculosis in the hepatic round ligament.
