| cerebral revascularization | Microsurgical revascularization to improve intracranial circulation. It usually involves joining the extracranial circulation to the intracranial circulation but may include extracranial revascularization (e.g., subclavian-vertebral artery bypass, subclavian-external carotid artery bypass). It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularised tissue to the surface of the brain. (12 Dec 1998) |
| cerebral rheumatism | Central nervous system symptoms resulting from a rheumatic disease. Formerly seen primarily as a manifestation of rheumatic fever, now seen less frequently as a part of other diseases such as systemic lupus erythematosus. See: Sydenham's chorea. (05 Mar 2000) |
| cerebral sclerosis, diffuse | Diffuse progressive degeneration of the white matter of the brain, accompanied by mental deterioration, severe motor disturbances, and early death. (12 Dec 1998) |
| cerebral sinuses | Endothelium-lined venous channels in the dura mater. Synonym: sinus durae matris, cerebral sinuses, cranial sinuses, sinuses of dura mater, venous sinuses. (05 Mar 2000) |
| cerebral sphingolipidosis | Any one of a group of inherited diseases characterised by failure to thrive, hypertonicity, progressive spastic paralysis, loss of vision and occurrence of blindness, usually with macular degeneration and optic atrophy, convulsions, and mental deterioration; associated with abnormal storage of sphingomyelin and related lipids in the brain. Four types are recognised as clinically and enzymatically distinct: 1) infantile type (Tay-Sachs disease, GM2 gangliosidosis) due to a deficiency of hexosaminidase A; 2) early juvenile type (Jansky-Bielschowsky or Bielschowsky's disease); 3) late juvenile type (Spielmeyer-Vogt disease; Spielmeyer-Sjogren disease; Batten-Mayou disease; ceroid lipofuscinosis); and 4) adult type (Kufs disease). Synonym: cerebral lipidosis. (05 Mar 2000) |
| cerebral sulci | The grooves between the cerebral gyri or convolutions. Synonym: sulci cerebri. (05 Mar 2000) |
| cerebral surface | The internal surface of certain cranial bones; they are the greater wing of the sphenoid and the squamous part of the temporal bone. Synonym: facies cerebralis. (05 Mar 2000) |
| cerebral tetanus | A type of local tetanus that follows wounds to the face and head; after a brief incubation (1-2 days) the facial and ocular muscles become paretic yet undergo repeated tetanic spasms. The throat and tongue muscles may also be affected. Synonym: cerebral tetanus, head tetanus, hydrophobic tetanus, rose cephalic tetanus, Rose's cephalic tetanus. (05 Mar 2000) |
| cerebral thrombosis | Clotting of blood in a cerebral vessel. (05 Mar 2000) |
| cerebral trigone | Origin: L, an arch. <anatomy> An arch or fold; as, the fornix, or vault, of the cranium; the fornix, or reflection, of the conjuctiva. Esp, two longitudinal bands of white nervous tissue beneath the lateral ventricles of the brain. Source: Websters Dictionary (01 Mar 1998) |
| cerebral tuberculosis | Inflammation of the cerebral leptomeninges marked by the presence of granulomatous inflammation; it is usually confined to the base of the brain (basilar meningitis, internal hydrocephalus) and is accompanied in children by an accumulation of spinal fluid in the ventricles (acute hydrocephalus). Synonym: cerebral tuberculosis. (05 Mar 2000) |
| cerebral ventricle neoplasms | Neoplasms located in the brain ventricles including the two lateral, third, and fourth ventricles. (12 Dec 1998) |
| cerebral ventricles | See: lateral ventricle, fourth ventricle, third ventricle, cavity of septum pellucidum. (05 Mar 2000) |
| cerebral ventriculography | Radiography of the ventricular system of the brain after injection of air or other contrast medium directly into the cerebral ventricles. It is used also for X-ray computed tomography of the cerebral ventricles. (12 Dec 1998) |
