Syringomyelia presenting as cricopharyngeal pseudostricture.

A 14-year-old boy was referred for evaluation of a cervical esophageal "stricture" diagnosed by upper gastrointestinal radiograph, which had been performed for evaluation of dysphagia and dysphonia of several months' duration. Neurological examination revealed several cranial nerve abnormalities and hyperreflexia, raising the suspicion of a cervicomedullary junction lesion. However, computed tomography of the head, neck, and spine was completely normal. Findings on the swallowing videofluoroscopy were interpreted as consistent with a stricture (a "tight constriction distal to the pyriform sinus"). However, no evidence for this was found by either esophagoscopy or esophageal manometry, which revealed a low-pressure cervical esophageal sphincter. Neurologic evaluation was pursued with magnetic resonance imaging, which revealed a large syrinx extending from C2 to T2 segments. We report this case to point out the importance of considering neurologic disease in the differential diagnosis of "stricture" of the cervical esophagus.
