AI Article Synopsis

  • Esophageal schwannoma is an uncommon benign tumor, and this study highlights findings from a specific case involving this condition.
  • Endoscopic ultrasound revealed that the tumor was situated in the muscular layer of the esophagus, presenting significant diagnostic information.
  • The FDG PET/CT scan showed high levels of FDG uptake, suggesting the tumor could resemble a malignant growth, indicating that schwannoma should be considered when diagnosing esophageal lesions that appear to be FDG-avid.

Article Abstract

Esophageal schwannoma is very rare. We describe FDG PET/CT findings in a case of benign esophageal schwannoma. Endoscopic ultrasound showed the tumor was located in the muscular layer of the esophagus. FDG PET/CT showed intense FDG uptake with SUV max of 10 of the tumor mimicking malignancy. This case indicates that schwannoma should be included in the differential diagnosis of esophageal FDG-avid lesions.
