Another CXR did not show worsening of the existing pneumothorax and confirmed that the pleural pigtail catheter was in the appropriate position. However, an urgent computed tomography (CT) scan of the head showed low-density opacities that are consistent with air in a watershed pattern on the right hemisphere with edema (Figure 1).
