Abstract:
A 13-year-old girl presented with dysphagia underwent contrast-enhanced CT and endoscopy. The CT revealed cervical esophageal wall thickening with heterogeneous enhancement. Microscopic examination of the biopsy specimen suggested a possible mesenchymal tumor. She underwent an 18 F-FDG PET/CT scan for staging. The scan showed local thickening of the cervical esophageal wall with heterogeneous and significantly elevated FDG activity. Subsequent immunohistochemical staining and fluorescence in situ hybridization confirmed the diagnosis of esophageal inflammatory myofibroblastic tumor.
