%X <B>UNASSIGNED: </B>Traumatic pneumocephalus is commonly encountered after basal skull fractures and rarely associated with blunt chest trauma. Here, we report a case of pneumocephalus caused by traumatic pneumothorax and brachial plexus avulsion.<BR><B>UNASSIGNED: </B>A 20-year-old male was admitted to our hospital following a motorcycle accident with complete paralysis of the right upper limb. 2 days later, follow-up computed tomography revealed a slight right pneumothorax, pneumomediastinum around the neck, and intracranial air without skull fracture. Air migrates into the subarachnoid space through a dural tear caused by a brachial plexus avulsion. The pneumocephalus immediately improved after the insertion of a chest drain.<BR><B>UNASSIGNED: </B>Pneumothorax combined with brachial plexus avulsion could lead to pneumocephalus. Immediate chest drainage might be the best way to stop the migration of air; however, care should be taken to not worsen cerebrospinal fluid leakage.
