Mount Fuji Sign-CT

"The Mount Fuji sign on CT scans of the brain is useful in discriminating tension pneumocephalus from nontension pneumocephalus. Tension pneumocephalus can be a neurosurgical emergency, unlike nontension pneumocephalus. Tension pneumocephalus occurs most commonly after the neurosurgical evacuation of a subdural hematoma."
The collapsed frontal lobes and the widening of the interhemispheric space between the tips of the frontal lobes have the appearance of the silhouette of Mount Fuji —hence, the Mount Fuji sign.

Sir ,

This may not be true always . We had an exceptional case which we published recently in the European Journal of Radiology .
