A Ahyai, and O Spoerri

Treatment of traumatic brain oedema leads to a decrease in raised intracranial pressure, and this may facilitate formation or progression of pneumatocephalus. Lumbar puncture or lumbar CSF drainage for treatment of CSF-rhinorrhoea/otorrhoea is occasionally responsible for the occurrence or enhancement of pneumatocephalus. Pneumatocephalus with radiological absence of fracture of the skull and absence of CSF leakage signifies communication between rhinocranium and encephalocranium: this supplies evidence of an open head injury. Post-traumatic opacification of the sphenoid sinus and presence of suprasellar air, as well as traumatic lesion of the optic chiasma are pathognomonic for the presence of a fracture of the planum sphenoidale. Computerised axial tomography is superior to plain skull x-rays in the localisation of intracerebral air.

D011007	Pneumocephalus	Presence of air or gas within the intracranial cavity (e.g., epidural space, subdural space, intracerebral, etc.) which may result from traumatic injuries, fistulous tract formation, erosions of the skull from NEOPLASMS or infection, NEUROSURGICAL PROCEDURES, and other conditions.

D001929	Brain Edema	Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

D012887	Skull Fractures	Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).

D013100	Sphenoid Bone	An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).
