Mount Fuji Sign in tension pneumocephalus

A 64-year-old male reported 36 hours after sustaining injuries to head and face in a road-traffic accident. He was conscious and alert with Glasgow Coma Scale of 15/15. Non-contrast computed tomography (NCCT) head revealed fracture of frontal sinus extending to right orbital roof with pneumocephalus depicting classical Mount Fuji sign (Fig 1). Since patient was neurologically intact and did not have any cerebrospinal fluid leak, he was managed conservatively with decongestants and oxygen by mask. Recovery was uneventful with resolution of pneumocephalus.
