intracranial

Within the cranium.

Within the cranium.

• i. abscess — signs will vary depending on which parts of the brain are compressed and damaged. General signs include circling, rotation of the head and mental dullness. The CSF may contain inflammatory cells.
• i. hemorrhage — in the form of localizing hematomas with localizing signs occur very rarely in animals. May be multiple petechiae in asphyxial newborn lambs.
• i. pressure (ICP) — the pressure within the subarachnoidal fluid, which is present in the space between the skull and the brain. Intracranial pressure, like arterial blood pressure, can fluctuate markedly and quickly during straining to defecate. While signs of sustained increased intracranial pressure can be significant in the assessment of a patient with a neurological disorder, momentary increases in intracranial pressure are not in themselves necessarily detrimental.
• i. tumors — cause an increase in intracranial pressure and localizing signs, depending on the location of the tumor and the structures that are compressed.
