Air present between the cranium and the dura mater; the term is commonly used to indicate extradural or subdural air.

Chiang et al., published the first case about barotrauma-related pneumomediastinum ascending to cranial cavity leading to the tension pneumocranium. Herein, the authors reported an extremely rare case of shunt-related complication with early onset tension pneumocranium following pneumomediastinum. The authors also discussed the possible mechanism and management method to deal with it 1).

We describe two cases of post-operative extradural tension pneumocephalus occurring following free myocutaneous latissimus dorsi flap reconstruction of anterior cranial defects following extirpation of advanced recurrent skin carcinomas. These cases illustrate the variation in clinical presentation of this condition, the importance of prompt recognition, urgent radiological investigation and timely decompression, and potential management strategies for minimising the risk of recurrent symptoms 2).
