Dysphagia with recurrent severe aspiration due to cervical diffuse idiopathic skeletal hyperostosis (Forestier's disease).

Dysphagia is a common symptom in patients presenting to the gastroenterologist. However, extraluminal causes of dysphagia may be missed by endoluminal diagnosis alone. This case report presents a 72-year-old man with slowly progressive dysphagia that occurred with the ingestion of certain solid foods and was intermittently associated with severe aspiration. Esophagogastroduodenoscopy and barium swallow study were both normal. However, a conventional x-ray and computed tomography (CT) scan of the neck revealed diffuse idiopathic skeletal hyperostosis (Forestier's disease) of the anterior cervical spine (C2-C7). Fiber endoscopic evaluation of swallowing (FEES) revealed functionally incomplete emptying of the oral cavity during swallowing, and the patient reported dysphagia score (EAT-10) was 23 (normal < 3). Surgical removal of the hyperostosis (C3-C6) resulted in immediate and sustained improvement in dysphagia at 3 months.
