[Laryngo-tracheal involvement in chronic atrophic polychondritis. X-ray computed tomographic aspects]. / Atteinte laryngo-trachéale d'une polychondrite chronique atrophiante. Aspects tomodensitométriques.

ABSTRACT

CT patterns of a relapsing polychondritis affecting the laryngeal cartilages are reported in a 42-year-old man with a 10-year medical history of this disease, corresponding to an irregular enlargement of the cricoid, thyroid cartilages and tracheal rings, with a moderate endoluminal narrowing. CT is useful to differentiate this rare inflammatory disease from others causes of airway narrowing, and could help in certain cases of diagnosis of beginning polychondritis.
