Day 1 postoperative computed tomography of the brain (CTB) showed a small bifrontal pneumocephalus [Figure 1a]. CTB demonstrated an expanding pneumocephalus with mass effect [Figure 1b]. This was decompressed via bilateral frontal burr holes and CTB showed a slight reduction in the volume of the pneumocephalus [Figure 1c]. Postoperative CTB showed a significant reduction in the size of the pneumocephalus [Figure 1d].
