| brain mantle | Origin: L. See Pall the garment. 1. A large, square, woolen cloak which enveloped the whole person, worn by the Greeks and by certain Romans. It is the Roman name of a Greek garment. 2. A band of white wool, worn on the shoulders, with four purple crosses worked on it; a pall.

| brain metastases | <oncology, radiology> 10% of intracranial mass lesions are metastasis, 10-38% of patients with systemic cancer have brain metastasis: adults: lung, breast, GU tract, colon/rectum, melanoma, sinuses. children: neuroblastoma, embryonal rhabdomyosarcoma, Wilms tumour. Location: most in middle cerebral artery distribution at the cortex, 20% in posterior fossa. See also: haemorrhagic metastasis. (08 Mar 2000) |

| brain oedema | Brain swelling due to increased volume of the extravascular compartment from the uptake of water in the neuropile and white matter. See: brain swelling. Synonym: brain oedema. (05 Mar 2000) |
| brain potential | <physiology> The electrical charge of the brain as compared to a point on the body; the potential may be steady (DC potential) or may fluctuate at specific frequencies when recorded against time, giving rise to the electroencephalogram. (05 Mar 2000) |

| brain tumour | <oncology, tumour> May be subdivided into primary brain tumours and the more common, secondary brain tumours. Primary brain tumours (for example astrocytoma, craniopharyngioma, glioma, ependymoma, neuroglioma, oligodendroglioma, glioblastoma multiforme, meningioma, medulloblastoma) arise from the uncontrolled proliferation of cells within the brain. Secondary brain tumours occur from the spread of cancer into the brain from a distant cancerous organ (metastasis). Common symptoms of a brain tumour include headache, nausea, vomiting, seizures, change in mentation, neurologic symptoms and loss of memory. (17 Dec 1997) |
| brain tumour calcifications | <radiology> Oligodendroglioma (90%), craniopharyngioma (70%), ependymoma (60%), choroid plexus papilloma (25%), low-grade astrocytoma (20%), meningioma (10%), others, dermoid, pineal tumours, lipoma, caveat: a calcified intraparenchymal tumour is most likely to be an astrocytoma due to higher overall incidence relative to other tumours mentioned above.

| brain tumours | Can be malignant or benign and can occur at any age. Primary brain tumours initially form in the brain tissue. Secondary brain tumours are cancers that have spread to the brain tissue (metastasized) from tissue elsewhere in the body. (12 Dec 1998) |
