E, 18FDG-PET maximum-intensity projection. 18FDG-PET/CT slices revealed increase uptake bilaterally in the helical cartilage and pinnae (arrows in Figs. 1AYC), confirmed by 3D volumeYrendered fusion image (arrows in Fig. 1D). Thoracic lesions were also found involving mediastinal and hilar lymph nodes, pleura, and pulmonary parenchyma (Fig. 1E). Otology & Neurotology 31:699Y70
