Pneumocephalus with gas-fluid level
Updates to Case Attributes
The patient was in a car accidentmotor vehicle collision 15 years ago but did not attend hospital. During these years she did not undergo any diagnostic examinationsimaging either. MRI examination showed a collection of gas (air) and fluid in the right hemisphere, which is presumed to be a chronic process due to the absence of the surrounding edemaoedema. The CT scan showed a fracture of the right ethmoid wall and the medial wall of the right orbit, which is the likely entry if site of the gas.

Updates to Study Attributes
There is a collection of air (gas)gas and fluid in the right hemisphere of the brain. The area of hypointense MR signal on T2 WI in the right frontal lobe is due to the presence of gas (air). The area of hyperintense MR signal on T2 WI in the right frontal and parietal lobes is due to fluid collection. There are no signs of surrounding edemaoedema.
