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.
软骨坏死是外照射放疗和气管插管已知的并发症。放疗是软骨坏死最常见的原因，因为治疗后会出现局部软骨缺血。长时间气管插管可导致软骨坏死，因为这与气管导管或其套囊对软骨的压力过大有关。环状软骨是最常受累的软骨。CT成像在检查中是不可或缺的一部分，尽管关于影像学表现的报道很少。我们报告了一例因气管插管通气导致软骨坏死的影像学和临床表现。该患者采用保守治疗，临床效果良好。
