case_images: Although X-ray and computed tomography (CT) images did not indicate any change of the operative region ( Figure 2 ), the thoracic CT and MRI of the brain demonstrated metastatic lesions of the rib, left lung lobe, scalp, skull, and meninges ( Figures 3 ,  4 ).
case_images: Thoracic CT demonstrated the metastatic lesions of the rib, left lung lobe. White arrows indicate the lesions.
