Case 223: Arytenoid Dislocation

Radiology. 2015 Nov;277(2):607-11. doi: 10.1148/radiol.2015140145.


A 71-year-old man with a history of atrial fibrillation refractory to medical therapy and lung cancer status after left upper lobectomy presented to our hospital for elective cardioversion and rate control with tikosyn. Overnight, the patient became unresponsive and was found to be in a state of cardiogenic shock. A code was called, and he was stabilized after cardioversion and bedside intubation. His stay in the intensive care unit was complicated by ventilator-associated pneumonia. The patient subsequently underwent multiple failed extubation attempts, requiring two additional reintubations. He was finally extubated 18 days after his initial admission to the intensive care unit. After he was discharged, he reported a hoarse voice and was only able to whisper. His voice varied in timbre and volume, and it became hoarser with use. Otolaryngology evaluation, including laryngoscopy and video stroboscopy, showed immobility of the right vocal cord. He was referred for speech therapy, and a computed tomographic (CT) examination of the neck was ordered.
