CT and (18F)FDG PET/CT Findings of Esophageal Squamous Cell Papillomatosis: A Case Report

ABSTRACT

Esophageal squamous cell papillomatosis is a rare disorder that is usually found incidentally on an upper gastrointestinal endoscopy examination or autopsy. A 70-year-old woman presented with a two-month history of dysphagia and abdominal discomfort. A chest CT scan showed diffuse marked thickening of the esophageal wall along the entire length and multiple small enhancing polypoid projections in the distal esophagus. Diffuse circumferential FDG uptake in the entire esophagus was seen on [18F] FDG PET/CT. Squamous papillomatosis was diagnosed by an endoscopic biopsy. We report a case of extensive esophageal papillomatosis with imaging features on CT and [18F] FDG PET/CT, with a review of the clinical literature.
