Last reviewed 01/2018
Many organisms may be implicated in the aetiology of meningitis.
These organisms produce a variety of clinical events, including:
- acute aseptic meningitis - a benign, self limiting condition caused by viruses
- acute pyogenic meningitis - a potentially lethal condition caused by many bacteria
- chronic meningitic illness may be produced by organisms such as fungi and mycobacteria and other processes, e.g. tumour cells, contrast media, blood from subarachnoid haemorrhage, and drugs
