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 .
