Chondronecrosis is a known complication of external beam radiation therapy and endotracheal intubation. Radiation therapy is the most common cause of chondronecrosis owing to local cartilage ischaemia following treatment. Prolonged endotracheal intubation can lead to chondronecrosis as it is associated with excessive pressure on the cartilage by the endotracheal tube or its cuff. The cricoid ring is the most commonly affected cartilage. CT imaging is an integral part of the workup, although reports on imaging appearances are scant. We report the imaging and clinical presentation of a case of chondronecrosis secondary to the use of endotracheal tube ventilation. The patient was managed conservatively with good clinical outcome.

Case Report
A-21-year-old-male patient presented with hoarseness of voice and occasional difficulty in breathing. The patient was involved in a road traffic accident 9 months ago and had sustained a head injury. He underwent surgery for depressed fracture of the parietal bone. The patient was managed on endotracheal intubation for 7 days, followed by elective tracheostomy. Later, he was put on T-piece mode of ventilation. Subsequently, he was decannulated successfully after 4 months. 10 days following decannulation, the patient developed change of voice—hoarse in nature and breathy in quality—chronic cough and difficulty in breathing.
