| APM | Acute Purulent Meningitis |
| cryptococcal meningitis | <pathology> An opportunistic infection caused by the fungus Cryptococcus neoformans and involving the membranes surrounding the brain and spinal cord. Symptoms may include severe headache, confusion, sensitivity to light, blurred vision, fever and speech difficulties. Left untreated, the disease can lead to coma and death. Standard treatments are amphotericin B (induction) and fluconazole (maintenance). (09 Oct 1997) |

| Haemophilus influenza meningitis | <disease> A form of meningitis caused by the bacterium haemophilus influenza. Inflammation of the membranes (meninges) covering the brain and spinal cord can result after infection with this organism. Influenza meningitis occurs most frequently in children under 5 years old. Onset may be sudden or occur more slowly after an upper respiratory infection. Symptoms and features include fever, headache, stiff neck, photophobia and mental status changes. Infants may be irritable and exhibit poor feeding associated with fever. Severe cases may progress to seizures, coma and death. Treatment always includes high-dose systemic antibiotics and corticosteroids may also be used in some select cases. (27 Sep 1997) |
| serous meningitis | Acute meningitis with secondary external hydrocephalus. (05 Mar 2000) |
| neoplastic meningitis | Infiltration of subarachnoid space by neoplastic cells, typically medulloblastoma or metastatic carcinoma. Synonym: neoplastic arachnoiditis. (05 Mar 2000) |

| epidemic cerebrospinal meningitis | An acute infectious disease affecting children and young adults, caused by Neisseria meningitidis; characterised by nasopharyngeal catarrh, headache, vomiting, convulsions, stiffness in the neck (nuchal rigidity), photophobia, constipation, cutaneous hyperesthesia, a purpuric or herpetic eruption, and the presence of Kernig's sign. Fulminant form may cause Waterhouse-Friderichsen syndrome. Synonym: cerebrospinal fever, epidemic cerebrospinal meningitis. (05 Mar 2000) |
| epidural meningitis | Inflammation of the outer surface of the dura mater. Synonym: epidural meningitis, external meningitis. (05 Mar 2000) |
| tuberculous meningitis | 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) |
| external meningitis | Inflammation of the outer surface of the dura mater. Synonym: epidural meningitis, external meningitis. (05 Mar 2000) |
