| cerebrospinal meningitis | <microbiology, neurology> Inflammation of the meninges. When it affects the dura mater, the disease is termed pachymeningitis, when the arachnoid and pia mater are involved, it is called leptomeningitis or meningitis proper. See also: aseptic meningitis.

| cerebrotendinous cholesterinosis | A disorder with deposition of cholestanol in the brain and other tissues and high levels in plasma but with normal cholesterol level; characterised by progressive cerebellar ataxia beginning after puberty, juvenile cataracts, spinal cord involvement, and tendinous or tuberous xanthomata; autosomal recessive inheritance. Probably due to a defect in hepatic mitochondrial 26-hydroxylase in bile acid biosynthesis. Synonym: cerebrotendinous cholesterinosis. (05 Mar 2000) |
| cerebrotendinous xanthomatosis | A disorder with deposition of cholestanol in the brain and other tissues and high levels in plasma but with normal cholesterol level; characterised by progressive cerebellar ataxia beginning after puberty, juvenile cataracts, spinal cord involvement, and tendinous or tuberous xanthomata; autosomal recessive inheritance.
