Dysphagia due to Diffuse Idiopathic Skeletal Hyperostosis

Abstract EN

Diffuse idiopathic skeletal hyperostosis (DISH) is usually asymptomatic.

However, rarely, it causes dysphagia, hoarseness, dyspnea, snoring, stridor, and laryngeal edema.

Herein, we present a patient with DISH causing dysphagia.

A 70-year-old man presented with a 4-month history of sore throat, dysphagia, and foreign body sensation.

Flexible laryngoscopy revealed a leftward-protruding posterior wall in the hypopharynx.

Computed tomography and magnetic resonance imaging revealed a bony mass pushing, anteriorly, on the posterior hypopharyngeal wall.

Ossification included an osseous bridge involving 5 contiguous vertebral bodies.

Dysphagia due to DISH was diagnosed.

His symptoms were relieved by conservative therapy using anti-inflammatory drugs.

However, if conservative therapy fails and symptoms are severe, surgical treatments must be considered.
