Case Studies

Lesions of the arytenoid region in a patient with exertional dyspnoea

A Nagai, H Matsumiya, M Hayashi, T Kanemura, S Yasui, and K Konno

A 63 year old woman presented with a 3 year history of exertional dyspnoea. Spirometry suggested extrathoracic airway obstruction (decreased inspiratory flow and saw-tooth pattern of flow-volume curves), and bronchoscopy revealed structural lesions and a trembling motion in the arytenoid region, causing upper airway obstruction on forced respiratory efforts. As there were no abnormal findings other than the lesions, the exertional dyspnoea was probably caused by impaired movement of the arytenoid region.
