Case report demonstrates better lesion detection in relapsing polychondritis using Ga-68 FAPI PET/CT, suggesting improved diagnostic accuracy.
Relapsing polychondritis is an autoimmune inflammatory disorder characterised by immune-mediated destruction of cartilaginous and proteoglycan-rich tissues, driven by autoantibodies against type II collagen and activation of macrophages and fibroblasts. We report a case of a 50-year-old female who presented with multisystemic involvement and nonspecific tracheal inflammation. F-18 FDG (Fluorodeoxy glucose) and Ga-68 FAPI PET/CT (Fibroblast Activating Protein Inhibitor) were done for evaluation. Ga-68 FAPI PET/CT showed enhanced lesion detection over F-18 FDG PET/CT in this case of Relapsing Polychondritis.
