| intracranial granulomatous arteritis | A small vessel, giant cell arteritis that affects only intracranial blood vessels, of unknown aetiology, and with diverse clinical manifestations, including those seen with an involving cerebral tumour, and with a low grade meningitis, leading to infarction of one portion of the cerebrum or cerebellum.

| intracranial haematoma | See: intracranial haemorrhage. Intramural haematoma, a haematoma in the wall of a structure, such as the bowel or bladder, usually resulting from trauma. (05 Mar 2000) |
| intracranial haemorrhage | Escape of blood within the cranium due to loss of integrity of vascular channels, frequently forming haematoma. (05 Mar 2000) |
| intracranial hypertension | Increased pressure of the cerebrospinal fluid. If symmetrically distributed it may have few neurologic symptoms (e.g., pseudotumour cerebri), but if it is asymmetrical (as in hydrocephalus), neurological symptoms are often severe. (12 Dec 1998) |
| intracranial hypotension | Subnormal pressure of the cerebrospinal fluid. It is most commonly found after lumbar puncture and is associated with headache, nausea, vomiting, stiffness of the neck, and sometimes fever. It may also result from dehydration. (12 Dec 1998) |
| intracranial mycotic aneurysm | <radiology> 3% of all intracranial aneurysms; multiple in 20%, source: subacute bacterial endocarditis (65%), acute bacterial endocarditis (9%), menigitis (9%), septic thrombophlebitis (9%), myxoma, location: peripheral to first bifurcation of major vessel (64%), often near the surface of brain (especially over convexities), Note: develops recurrent bleeding more frequently than congenital aneurysms See: mycotic aneurysm (12 Dec 1998) |
| intracranial part of optic nerve | <anatomy, nerve> The portion of the optic nerve between the optic canal and the optic chiasm. Synonym: pars intracranialis nervi optici. (05 Mar 2000) |
| intracranial part of vertebral artery | See: vertebral artery. (05 Mar 2000) |
| intracranial pneumatocele | A collection of gas within the skull, in the brain, or in the meninges. Synonym: intracranial pneumocele. (05 Mar 2000) |
| intracranial pneumocele | A collection of gas within the skull, in the brain, or in the meninges. Synonym: intracranial pneumocele. (05 Mar 2000) |
| intracranial pressure | <physiology> The pressure the cerebrospinal fluid exerts on the brain. (27 Sep 1997) |
| intracranial tuberculoma | <neurology> A well-circumscribed mass found cortically or subcortically in the cerebral or cerebellar hemispheres. In under-developed countries where tuberculosis is endemic these lesions are quite common. Management of intracranial tuberculomas includes antituberculosis chemotherapy and neurosurgical evacuation of tuberculomas singly or in combination. (04 Jul 2000) |
| extracranial-intracranial bypass | A vascular shunt created by the anastomosis of an extracranial vessel to an intracranial vessel, usually, the superficial temporal artery to a cortical branch of the middle cerebral artery. (05 Mar 2000) |
