Mechanical oesophageal dysphagia is caused by either an extrinsic compression of oesophageal lumen or intrinsic pathologies of oesophageal wall. The oesophagus may be compressed externally by an enlarged thyroid gland, vascular pathologies, a mediastinal mass, or a retropharyngeal abscess.1 In addition, skeletal pathologies such as anterior osteophytic bridges due to diffuse idiopathic skeletal hyperostosis (DISH), degenerative osteophytes, congenital bone bars, atlantoaxial dislocation, anterior herniation of calcified nucleus pulposus, rheumatoid pannus of the cervical spine, and ankylosing spondylitis causing anterior longitudinal ligament calcification can all produce external compression of the oesophagus and consequent dysphagia.2,3
