Imaging findings
A chest radiograph shows gas-filled structures and an unusual appearance of the whole right hemithorax. CT shows a dilated colonic interposition conduit, used to replace the esophagus after lye ingestion, running in the anterior mediastinum and compressing the right lung.
Key takeaways
Colonic interposition conduits are used to replace a destroyed esophagus, often after caustic injury, and typically run in the anterior mediastinum. They can dilate over time and may develop motility issues. While they can compress adjacent lung, if the conduit is placed later in life, lung hypoplasia is less likely.
