Imaging Findings

(A) Chest radiograph demonstrates multiple lower lung zone–predominant well-circumscribed pulmonary nodules (arrows). (B) Energy-subtracted chest radiograph demonstrates the pulmonary nodules to better advantage (arrows). (C) Contrast-enhanced computed tomography (CT; lung window) at the level of the coronary sinus confirms multiple well-circumscribed noncalcified pulmonary nodules (arrows). (D) Contrast-enhanced CT (soft-tissue window) at the level of the vocal cords demonstrates a large heterogeneous laryngeal mass (arrow) with right jugular lymphadenopathy.
