Granulomatous Inflammation of Liver Mimicking Malignancy on 68 Ga-FAPI PET/CT.

68 Ga-FAPI has emerged as an alternative tracer for tumor imaging, as FAP is expressed in >90% of epithelial cancers. Although promising data on this new radiotracer are increasing, false-positive results due to nonmalignant diseases with FAP uptake are also reported (for instance, chronic inflammation, arthritis, and fibrosis). In this case, we demonstrated 68 Ga-FAPI PET/CT involvement in a patient diagnosed with hepatic sarcoidosis.
