mount Fuji sign
Post-traumatic
tension pneumocephalus: CT findings. Bilateral subdural pneumocephalus (the ""Mount Fuji sign"").
Mount Fuji sign is seen on cross-sectional imaging and is indicative of a tension pneumocephalus.
The sign refers to the presence of gas (pneumocephalus) between the tips of the frontal lobes with a heaped-up appearance giving the silhouette-like appearance of Mount Fuji . It suggests that the pressure of the gas is at least greater than that of the surface tension of cerebrospinal fluid between the frontal lobes . The sign is caused by cortical veins tethering the frontal lobes, resulting in their striking appearance .
The appearance of this sign often warrants immediate surgery to prevent permanent neurological damage. However, conservative management in patients with no signs of raised intracranial pressure has also been described .
