Figure 1. Imaging studies on admission.
(a) Contrast-enhanced computed tomography (CT) on admission demonstrated an invasive mass lesion with non-homogenous enhancement. The mass measured 85 × 67 mm and was located adjacent to S7 of the right lung, with bone infiltration and a compression fracture of the thoracic vertebrae. A low-density area (white arrow) was partially visible on the left side of the mass. (b) A magnetic resonance (MR) T2-weighted image showed that the mass spiraled up the pulmonary vessels (white arrows) and markedly infiltrated the thoracic vertebrae.
