Pneumocephalus is often detected in patients with trauma. However, it is difficult to find studies on position change of intracranial air according to the patient position observed on skull X-rays (erect and supine views). This is because skull X-rays are rarely performed in erect position for patients with head injury. We report a case of location change of intracranial air associated with patient position change observed in the skull X-ray of a patient with traumatic pneumocephalus. To the best of our knowledge, no such cases have previously been reported in English literature.
