title: Pseudomass lesions due to occult trauma of the larynx.
abstract: Fracture of the laryngeal skeleton is best diagnosed by computed tomography. Deformity of the laryngeal cartilage may cause signs and symptoms that suggest neoplastic submucosal mass. Symptoms may not develop until years after the original injury. A series is described in which the patients demonstrate the characteristic signs, symptoms, and computed tomographic appearance of old, often forgotten, fractures of the thyroid cartilage. The diagnosis is best made by computed axial tomography of the neck.
