CTICasesEsophageal Carcinoma with Radiographic Correlation

Imaging findings
Frontal radiograph showed an extra bump in the lower mediastinum, with the descending aorta and azygos esophageal recess appearing convex. Lateral view was non-contributory. CT correlation revealed fluid and dilation in the esophagus, and a clearly abnormal, thickened esophagus with a narrow lumen protruding to the left, and a large lesion. Esophagram confirmed irregular shape, classic for carcinoma.
Key takeaways
Esophageal carcinoma can manifest on chest radiographs as subtle mediastinal contour abnormalities, such as an extra bump in the lower mediastinum or convexity of the azygos esophageal recess. CT and esophagram provide definitive diagnosis by showing esophageal thickening, luminal narrowing, and tumor mass.
