OBJECTIVE: The purpose of this study was to evaluate the esophagographic and CT findings of corrosive esophageal cancer. MATERIALS AND METHODS: The records of all patients who presented with corrosive esophageal strictures at one institution between June 1989 and April 2015 were retrospectively identified. The search yielded the records of 15 patients with histopathologically proven esophageal cancer. Esophagograms (13 patients) and chest CT images (14 patients) were interpreted independently by two reviewers. Esophagographic findings included the location of tumor, morphologic type, presence and length of mucosal irregularity, presence of asymmetric involvement, and presence of rigidity. CT findings included presence and type of esophageal wall thickening, pattern of enhancement, presence of periesophageal infiltration, and presence of hilar or mediastinal lymphadenopathy. RESULTS: Esophagography showed that the tumor was involved with the stenotic portion in 10 of the 13 patients (76.9%). The most common morphologic feature was a polypoid mass, in 10 patients. In 12 patients (92.3%), mucosal irregularities were observed; the mean affected length was 4.92 cm. Asymmetric involvement and rigidity were observed in nine patients (69.2%). On CT scans, eccentric wall thickening was observed in 10 of the 14 patients (71.4%), homogeneous enhancement in nine (64.2%), and periesophageal infiltration in 11 (78.5%). CONCLUSION: Esophagography commonly shows corrosive esophageal cancer as a polypoid mass with long-segment mucosal irregularities at the stenotic portion, asymmetric involvement, and rigidity. CT shows eccentric esophageal wall thickening with homogeneous enhancement and periesophageal infiltration, which are suggestive of the development of malignancy in patients with corrosive esophageal strictures.
