CTICasesIatrogenic esophageal perforation post-mediastinoscopy
Imaging findings
CT shows pneumomediastinum and subcutaneous gas following mediastinoscopy. Barium esophagram shows extravasation of contrast in the subcarinal space, accumulating in the surgical cavity and mimicking a diverticulum.
Key takeaways
Esophageal perforation is a serious complication of mediastinoscopy, typically occurring during biopsy of subcarinal (station 7) lymph nodes. Extravasated contrast can pool in the surgical cavity, resembling an esophageal diverticulum.
