Primary diffuse tracheobronchial amyloidosis: radiologic findings.

Reports detailing the radiologic features of tracheobronchial amyloidosis are scant and typically describe only the computed tomography findings of this disease. No reports have described the magnetic resonance (MR) findings of tracheobronchial amyloidosis. With this case, the authors describe the radiologic findings in a patient with diffuse tracheobronchial amyloidosis, focusing particularly on the MR and bone scintigraphy findings in this disease.
