Radiologic diagnosis of chondroma and chondrosarcoma of the larynx.

The radiographic findings in chondroma and chondrosarcoma of the larynx basically comprise a discreet soft tissue mass on plain lateral and anteroposterior film, a smooth mucosal outline to the lesion, calcification, with either peripheral or central stippling and ossification. Secondary signs are also noted. Definition of these criteria are illustrated in order to apply these findings to the radiographic diagnosis of chondroma and chondrosarcoma of the larynx.
