| 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 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) |
| abdominal pressure | Pressure surrounding the bladder; estimated from rectal, gastric, or intraperitoneal pressure. (05 Mar 2000) |
| absolute pressure | Pressure measured with respect to zero pressure. Compare: gauge pressure. (05 Mar 2000) |
| acoustic pressure | In ultrasound, the instantaneous value of the total pressure minus the ambient pressure; unit is pascal (Pa). (05 Mar 2000) |
| air pressure | The force per unit area that the air exerts on any surface in contact with it. Primarily used for articles pertaining to air pressure within a closed environment. (12 Dec 1998) |
| atmospheric pressure | The pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned. (12 Dec 1998) |
| back pressure | Pressure exerted upstream in the circulation as a result of obstruction to forward flow, as when congestion in the pulmonary circulation results from stenosis of the mitral valve or failure of the left ventricle. (05 Mar 2000) |
