| smell-brain | Origin: NL, fr. Gr, the nose + the brain. <anatomy> The division of the brain in front of the prosencephalon, consisting of the two olfactory lobes from which the olfactory nerves arise. The term is sometimes used for one of the olfactory lobes, the plural being used for the two taken together. Source: Websters Dictionary (01 Mar 1998) |
| split brain | A brain in which the corpus callosum and usually the anterior and posterior commissures have been sectioned; usually to treat certain refractory epilepsies. (05 Mar 2000) |
| developmental brain tumours | <radiology> 1% of all brain tumours, germ-cell tumours, epidermoid more than dermoid more than > Teratoma, usually midline, craniopharyngioma, colloid cyst, lipoma, hamartoma (12 Dec 1998) |
| diffuse brain atrophy | A form of dementia caused by destruction (atrophy) of the frontal lobes of the brain. This condition leads to the progressive deterioration of mental functioning. Incidence: 9 in 10,000 people in the general population. (27 Sep 1997) |
| dura mater of brain | The intracranial dura mater, consisting of two layers: the outer periosteal layer which normally always adheres to the periosteum of the bones of the cranial vault; and the inner meningeal layer which in most places is fused with the outer. The two layers separate to accommodate meningeal vessels and large venous (dural) sinuses. The meningeal layer is also involved in the formation of the various dural folds, such as the falx cerebri and tentorium cerebelli and is comparable to and continuous with the dural mater of the spinal cord. The cranial epidural space is then a potential space between the bone and the combined periosteum/periosteal layer of the dura mater realised only pathologically and is neither continuous with or comparable to the vertebral epidural space. Synonym: dura mater cranialis, dura mater encephali, cerebral part of dura mater, cranial epidural space. (05 Mar 2000) |
| infantile brain tumours | <radiology> Can be present at birth: choroid plexus papilloma, medulloblastoma, craniopharyngioma, ependymoma, astrocytoma, teratoma (12 Dec 1998) |
| organic brain syndrome | <syndrome> A constellation of behavioural or psychological signs and symptoms including problems with attention, concentration, memory, confusion, anxiety, and depression caused by transient or permanent dysfunction of the brain. Synonym: acute organic brain syndrome, OBS, organic mental syndrome. (05 Mar 2000) |
| enhancing brain nodule | <radiology> Metastases, infection, cysticercosis, histoplasmosis, tuberculosis, non-infectious inflammatory processes, sarcoidosis, multiple sclerosis, primary CNS lymphoma, subacute multiple infarcts see: ring lesions in brain (12 Dec 1998) |
| twixt-brain | <anatomy> The thalamencephalon. Source: Websters Dictionary (01 Mar 1998) |
| lateral fossa of brain | The deep depression of the basal surface of the forebrain that corresponds in position to the anterior perforated substance. Bounded medially by the optic tract and rostrally by the orbital surface of the frontal lobe, it extends laterally around the overhanging pole of the temporal lobe into the Sylvian fissure (sulcus lateralis). Synonym: fossa lateralis cerebri, fossa of Sylvius, lateral fossa of brain, vallecula sylvii. (05 Mar 2000) |
| bladder neoplasms | Cancers or tumours of the bladder. The majority of bladder neoplasms are of the transitional cell variety and are usually papillary and multicentric. (12 Dec 1998) |
| bone marrow neoplasms | Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as myeloma. most bone marrow neoplasms are metastatic. (12 Dec 1998) |
| breast neoplasms, male | Any neoplasms of the male breast. These occur infrequently in males in developed countries, the incidence being about 1% of that in females. Two-thirds of patients present with intraductal carcinoma. The average age of onset is 60 years for men. Orchiectomy was the standard treatment but it has been replaced by tamoxifen as the initial therapy since oestrogen-receptor-positive tumours are predominant in males. Orchiectomy and mastectomy may be used if initial drug therapy is not successful. The prognosis is worse than that for females. (12 Dec 1998) |
| vascular neoplasms | <oncology> Neoplasms located in vascular tissue or specific veins. They are differentiated from neoplasms, vascular tissue which are neoplasms composed of vascular tissue, such as angiofibroma or haemangioma. (12 Dec 1998) |
