However, CT and MRI scans revealed to the patient's medical team he only had a large, empty void called pneumocephalus
, where the right frontal lobe of his brain should have been.
CT scan revealed that the FBSOS had penetrated through the left nasal cavity to the sphenoidal planum and reached the right thalamus, with an intracranial penetration of 5 cm as well as pneumocephalus
[Figure 2]b and [Figure 2]c.
Noncontrast head CT demonstrated bifrontal and convexial (intrahemispheric) intracranial air, also known as pneumocephalus
(-1000 Hounsfield units), on the bone window.
Computed tomography (CT) revealed a severely comminuted right naso-orbital-ethmoid (NOE) complex fracture, posteriorly displaced fracture segments from the anterior table of the frontal sinus and frontal process of the maxilla, a comminuted posterior table fracture, obstruction of the frontal sinus outflow tract (FSOT), and a small area of pneumocephalus
Supra-tentorial extension showed occipital linear fracture in 17(50%), pneumocephalus
in posterior fossa and supra-tentorial in 8(23.
Next, the brain was surveyed for any evidence of pneumocephalus
, hydrocephalus, cerebral oedema, midline shift, or compression of the subarachnoid cisterns at the base of the brain.
A case of pneumocephalus
and meningitis as a complication of silent otitis media.
Direct (coup) impact the left temporal and occipital scalp result in temporal bone fracture and pneumocephalus
Multifocal tiny artifacts from air were seen in the thecal sac and epidural collection suggestive of the connection of the mass with the spinal canal and explaining the source of large pneumocephalus
and central nervous system infection (Figure 4).
On radiological examination X-ray skull also revealed pneumocephalus
Perioperative lumbar drain placement: an in dependent predictor of tension pneumocephalus
and intracranial complications following anterior skull base surgery.
Penetrating neck trauma causing tracheal rupture, spinal cord injury, and massive pneumocephalus
