FIGURE 1 PET-CT images disclosing severe circumferential lower esophageal wall thickening associated with mild mural FDG avidity and associated luminal narrowing. A, PET image, (B) CT images, and (C), fused images. The arrow indicates the esophageal abnormality. PET, positron emission tomography, CT, computed tomography; FDG, fluorodeoxy-D-glucose.

FIGURE 2 Midesophagus mucosal biopsies (hematoxylin and eosin stain). Representative images taken at (A) 200× and (B) 400× magnification demonstrate active esophagitis with surface ulceration and fibrinopurulent exudate (blue arrows), and granulation tissue formation (black arrows). The predominantly neutrophilic infiltrate has admixed eosinophils. Stains for microorganisms were negative (not shown).
