Chondrosarcoma of the larynx is a rare malignant cartilaginous neoplasm. To date, the serial sectioned laryngeal specimens of this disease have not been correlated with the pre-operative computed tomographic findings. A retrospective analysis of 833 serially sectioned laryngeal specimens found chondrosarcoma in six cases (0.72%), of which four cases had a pre-surgical computed tomography (CT). Radiologic axial sections were compared with microscopic sections in the same plane. Whole organ sections showed the tumor to have an expansile growth pattern, showing little impulse to infiltrate adjacent cartilage. CT scanning successfully predicted the diagnosis of a cartilage neoplasm prior to surgery, and accurately reflected the site and extent of laryngeal involvement. We conclude that CT is a reliable method of evaluating chondrosarcoma of the larynx, thereby predicting the feasibility of partial laryngeal resection.
