Imaging findings
An initial CT, performed for chest pain in a patient with an esophageal stent for cancer, showed subtle air outside the stent lumen and some material/air within the stent. A follow-up CT with contrast medium later clearly demonstrated disruption of the esophagus near the stent, with both contrast medium and air extravasating outside the esophageal lumen into the mediastinum. Complications related to the pleural space were also noted.
Key takeaways
Esophageal perforation, especially in the context of a stent for esophageal cancer, can present with subtle initial findings like extraluminal air. The use of contrast studies is crucial for confirming the diagnosis and delineating the extent of perforation. Prompt recognition is important due to potential mediastinal and pleural complications.
