An 80-year old woman complained of a 1-month history of dry cough. Bronchoscopy and tracheobronchial biopsy revealed tracheobronchial amyloidosis. Compted tomography scan showed narrowing of the trachea with intraluminal nodularity. Whole body and single photon emission computed tomography 99mTc pyrophosphate scan revealed diffuse uptake in the tracheobronchial tree, liver, and myocardium — with a unique biventricular pattern. Scintigraphy may assist in establishing the diagnosis, as well as in evaluating systemic involvement in amyloidosis.
