The use of covered self-expanding stents in palliation of benign and malignant conditions of the esophagus has gained widespread acceptance in the management of dysphagia [14]. Known complications include distal migration, perforation, hemorrhage, incomplete expansion, tumor ingrowth, food impaction, aspiration, and recurrent dysphagia [59]. Discitis secondary to stent migration is extremely rare [10, 11]. We report a case of proximal stent migration with perforation inducing thoracic spondylodiscitis by direct local extension.

A 52-year-old man with metastatic esophageal adenocarcinoma treated by cisplatin and fluorouracil based chemotherapy with radiation developed severe dysphagia secondary to a malignant stricture in September 2005. A Polyflex® esophageal stent (Boston Scientific Corp, Natick, MA) with 18-mm internal diameter (ID) self-expanding to 23-mm ID × 120-mm-long silicone-coated plastic stent was successfully placed endoscopically with fluoroscopic guidance at our institut
