Pneumocephalus

As Pneumocephalus, also Pneumocephalus, rare Pneumencephalus, is the presence of gases, normally described as air within the cranial cavity. Cause of a Pneumocephalus is mostly a craniocerebral trauma with fracture of the skull bone. He is often seen after surgical procedures of the open brain or in the ENT field of medicine. A spontaneous or infection-related perforation at these sites partially paper-thin skull bone can result in the pneumatized sinuses, the middle ear and mastoid air to enter the intracranial space. This is sometimes an Oto or Rhinoliquorrhoe, the leakage of cerebrospinal fluid from the ear or nose, socialized.

In computed tomography ( CT), the gas bubbles have clearly dissociated from against the tissue, and some can be apparent even in a normal X-ray. In the current in the CT supine position, the gas bubbles normally rise and gather in front of the frontal lobes, this is referred to in the English language as "Mount Fuji sign".

The symptoms of a Pneumocepahlus are nonspecific and include headache, nausea and impaired consciousness. The symptoms caused by an increased intracranial pressure, this is accompanied by the possibility of a lower incarceration ( herniation ). The Pneumocephalus is usually an acute condition because air is absorbed relatively quickly.
