| meningitis, meningococcal | Inflammation in response to infection with neisseria meningitidis of the pia-arachnoid and the fluid residing in the space which it encloses as well as the fluid in the ventricles of the brain. This condition occurs most often in children and adolescents. (12 Dec 1998) |
| meningitis, pneumococcal | Meningitis caused by bacteria of the species streptococcus pneumoniae. This condition can develop as a complication of pneumococcal pneumonia; by extension from otitis, mastoiditis, or sinusitis; following a skull injury; or without preceding sign of infection elsewhere.

| meningitis, viral | Meningitis of viral origin usually due to picornaviruses, togaviruses, herpes viruses, paramyxoviruses, or arenaviruses. Symptoms include headache, malaise, nausea, fever, and neck stiffness. (12 Dec 1998) |
| meningo- | The meninges. Origin: G. Meninx, membrane (05 Mar 2000) |
| meningo-osteophlebitis | Inflammation of the veins of the periosteum. (05 Mar 2000) |
| meningocele | <anatomy, embryology> A protrusion of the membranes that cover the spine and part of the spinal cord through a bone defect in the vertebral column. It is due to failure of closure during embryonic life of bottom end of the neural tube, the structure which gives rise to the central nervous system (the brain and spinal cord). The term spina bifida refers specifically to the bony defect in the vertebral column through which the meningeal membrane and cord may protrude (spina bifida cystica) or may not protrude so that the defect remains hidden, covered by skin (spina bifida occulta). However, through usage the term spina bifida is gradually becoming synonymous The risk of all neural tube defects can be decreased by the mother taking folic acid during pregnancy. (21 Jun 1999) |
