Diagnosis With Brief Discussion

Reviewy

An uncommon disease characterized by deposition of protein precursors in various tissues throughout the body, most commonly the heart, liver and kidneys
Tracheobronchial amyloidosis is rare
Hoarseness, stridor, dyspnea, cough, hemoptysis and dysphagia
Middle-aged males, with a 2:1 predilection versus females
Radiographic findings
Tracheal wall thickening with calcifications
Narrowing of the tracheobronchial airway
Deposition can infrequently be solitary and mimic an endobronchial neoplasm

Amyloidosis may involve the tracheal posterior membrane
If high-attenuation thickening of the airway wall is seen with long-segment narrowing of the lumen, amyloidosis should strongly be suspected.
