Abstract

A 25-year-old woman experiencing dysphagia for 2 years underwent 18 F-FDG and Al 18 F-FAPI-74 PET/CT. The scans showed local thickening of the cervical and upper thoracic esophageal wall with several calcifications, accompanied by increased and heterogeneous FDG uptake and more intense FAPI activity. Histopathological analysis following thoracoscopic esophagectomy confirmed the diagnosis of esophageal inflammatory pseudotumor.
