[Pneumocephalus].

In this review, pneumocephalus - a pathological condition that most commonly refers to intracranial air located in the epidural or subdural spaces, the ventricles, or within the brain parenchyma - is investigated. Symptoms include headache and a pathognomonic splashing sound on head movement. In the absence of symptoms, conservative treatment is recommended, and in the presence of mild symptoms, oxygen therapy can accelerate intracranial air resorption. In some cases, simple pneumocephalus can progress to tension pneumocephalus, a potentially life-threatening condition that may require acute neurosurgical intervention.
