Diffuse idiopathic skeletal hyperostosis (DISH) with tracheal stenosis

Discussion:

This study shows extrinsic tracheal and esophageal compression by cervical spondylosis with marked anterior osteophytes and syndesmophytes affecting all cervical vertebrae consistent with diffuse idiopathic skeletal hyperostosis (DISH). This unusual etiology differs from tracheomalacia which decreased AP tracheal diameter in affecting the cervical segment instead of the thoracic segment and obvious extrinsic compression.
