Abstract:
A 57-year-old woman without hepatitis B or immunodeficiency presented with right upper abdominal pain and cough for 3 months. CT revealed one nodule in the lung and another in the liver. Both 18 F-FDG and 68 Ga-FAPI PET/CT showed increased tracer uptake in these 2 nodules, suggesting pulmonary carcinoma with hepatic metastasis. Finally, biopsies of these 2 nodules demonstrated the diagnoses of hepatic adenocarcinoma and pulmonary cryptococcosis. This case highlights that cryptococcosis can be FAPI-avid.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
