case_images: Computed tomography revealing intracranial pneumocephalus, evident at the top of the forehead, and compression of the bilateral frontal lobes.

case_images: TP at the top of the forehead and compression of the bilateral frontal lobes (Figure 1). Thus, an urgent cranial burr hole was performed.

case_images: Magnetic resonance imaging revealing pneumocephalus in the bilateral ventricles, with slight enlargement of the anterior horn of the lateral ventricles.

case_images: Thirty days postoperatively, the patient was admitted, and magnetic resonance imaging (MRI) revealed pneumocephalus in the bilateral ventricles, with slight enlargement of the anterior horn of the lateral ventricles (Figure 2).
case_images: Magnetic resonance imaging revealing a significant decrease in bilateral ventricular pneumocephalus.

case_images: MRI revealed that bilateral ventricular pneumocephalus decreased significantly (Figure 3).

case_images: Computed tomography revealing obvious pneumocephalus in the intracranial lobe, with compression of the brain tissue, and marked enlargement of the ventricles and fissures.

case_images: The brain tissue was compressed, and the ventricles and fissures were markedly enlarged (Figure 4).
case_images: PMC7311094_04
case_images: Computed tomography revealing a large area of pneumocephalus in the bilateral anterior cranial fossa. The frontal retention of air caused widening of the interhemispheric fissure, leading to a peaked appearance of the frontal poles, commonly referred to as "Mount Fuji sign".
