Mount Fuji is Not as “Active” as We Think

Background

A 65-year-old man presented with headache after a minor head injury (slip and fall with head lightly hitting a chair). Computed tomography (CT) revealed pneumocephalus with Mount Fuji sign. The possibility of tension pneumothorax was suspected. Because the patient did not have any signs of raised intracranial tension (ICT), after his proper counseling, surgery was withheld. In addition to this, the patient was not willing for any procedures; hence he was kept under observation. Repeat CT after 3 days and 1 week showed a progressive reduction in extra-axial air. Neurologic status of the patient remained stable, and he was discharged.
