Eosinophilic esophagitis: imaging features with endoscopic and pathologic correlation



We aim to review the imaging features of eosinophilic esophagitis on fluoroscopy and present how they can correlate with endoscopic and pathologic findings.


Eosinophilic esophagitis is a chronic immune-mediated disease that results in esophageal dysfunction. Upper esophagogastroduodenoscopy is high yield and required for biopsies to demonstrate the hallmark histologic findings of eosinophil-predominant inflammation. While esophagogastroduodenoscopy is currently mandatory for diagnosis, imaging findings can provide valuable information regarding the structural and functional properties of the esophagus. In addition, fluoroscopic studies may be very helpful in the setting of subtle findings and to evaluate fibrotic remodeling changes.


Radiologic examinations are a valuable tool in the assessment of eosinophilic esophagitis and can highlight changes of fibrostenotic disease, as overall narrowing can be more conspicuous fluoroscopically than endoscopically. As the disease increases in prevalence, it is critical that physicians recognize this condition and facilitate diagnosis and treatment.
