Figure 1 (A) Chest radiography: heterogeneous infiltration in the right upper lobe and homogeneous opacity in the left hilar region. (B)--(D) Chest Computed Tomography of the thorax: hypodense mass of 9 cm with well defined margins located in the mediastinum with extension to the left upper lobe, areas of consolidation in the right upper lobe associated with micro-nodular infiltration and ground-glass opacities. specialized neural crest cells associated with autonomic ganglia (paraganglia) 1.
