Unusual chondrosarcoma of the larynx: CT findings.
A case of a large low-grade mixed clear-cell and conventional chondrosarcoma of the larynx is reported involving the paraglottic space, the cricoid and thyroid cartilage and characterized by an unusual long clinical course over 22 years, although multiple recurrences occurred without developing metastases. Computed tomography suggests diagnosis by detecting calcifications and adequately demonstrates the extension of the tumor. Innersurface and surface-rendering images document the airway stenosis in all directions. The unusual feature of this case consists in the peculiar histopathological differentiation of the observed chondrosarcoma showing a large clear-cell component.
