case_images: Full-body 3D CT scan with intrathecal radioactive polymer infusion revealed the following: (1) incomplete herniation of the brain stem probably due to low CSF pressure; (2) dilation of endothoracic cyst, with more than 20 cm diameter, fully compressing left lung causing functional left pneumonectomy; and (3) possible communication of CSF with mesothoracic cystic mass (Figures 1(a), 1(b), and 2).
