 In discolored type of reflux esophagitis, radiologic findings include mild marginal irregularity, poor distensibility, luminal narrowing, and rough mucosal surface. In errosive and ulcerative type, shallow erosion could not always be detected by radiologic examination, and it is important to visualize the E-G junction precisely beatuse the ulcer mostly occurs along the E-G junction and may induce annular stricture.

 On the other hand, traction erosion along the longitudinal axis may show cylindrical narrowing from the E-G junction to upper portion of the esophagus as well as irregular margine with vague, longitudinal barium flecks. More deeper ulcer is relatively easy to be detected by radiologic examination and multiple lesions are common feature in that case. In protruded hypertrophic type, diffuse fine nodularity is the prominent radiologic feature.

 Most important differential diagnosis of the reflux esophagitis is superficial flat type and superficial depressed type of esophageal cancer. In reflux esophagitis with large ulcer, ulcer type of advanced cancer should be differentiated. As exceptional case, there is infiltrative type esophageal cancer mimicking to the reflux esophagitis. In cases which have mucosal irregularity or rigidity, malignant lesions should be considered. Furthermore its location or presence of hiatus hernia could be useful to differentiate reflux esophagitis from esophageal cancer. On the other hand, esophageal cancer may associate with hiatus hernia and this possibility should be kept in mind.

 Other diseases such as scleroderma, esophagitis secondary to moniliasis and virus are also the subjects to be differentiated from reflux esophagitis.
