[Localized tracheobronchial amyloidosis. A new case studied with x-ray computed tomographic and nuclear magnetic resonance. Review of the literature].
We report a new case of localized primary tracheobronchial amyloidosis revealed by haemoptysis and effort dyspnea. The CT scan image was a homogeneous and circumferential thickening of the bronchial wall measuring 282 on the Hounsfield scale. At magnetic resonance imaging the amyloid substance was a slightly less intense than fat tissue in T1 and T2-weighted sequences. Treatment using Yag laser photoresection stabilized the lesions with one year follow-up. The review of the literature enables us to summarize the clinical, endoscopic, morphological, prognostic and therapeutic features of tracheobronchial amyloidosis, as well as pathogenic hypotheses and relationship with tracheobronchopathia osteoplastica.
