CTICasesGastropleurocutaneous Fistula (Esophageal Conduit Leak)
Imaging findings
CT and an esophagogram in a patient post-esophagectomy show an esophageal conduit leak with oral contrast extravasating from the gastric conduit, tracking into the pleural space, and extending directly into the lateral chest wall, representing a gastropleurocutaneous fistula (empyema necessitans equivalent).
Key takeaways
Conduit leaks are serious complications of esophagectomy. Leakage of gastric contents can lead to mediastinitis, empyema, and rarely, extension through the chest wall to form a gastropleurocutaneous fistula.
