Immune compromised states e.g. AIDs
Inflammation due to disease
Poverty and deprivation
Which type of meningitis has these features:

Meningococcal meningitis
What are the characteristics of Tuberculous meningitis?
- fatal

What is METASTASES?
Secondary transfer of tumour cells from elsewhere in the body.
What type of tumour do these characteristics relate to?
- visual and hormonal effects
- removal through endoscopy in nose
Pituitory Tumour
What are the characteristics of Acoustic Neuroma?
- slow
- hearing problems
What are the characteristics of Extrinsic tumours?
- mostly benign—> rarely recur if removed
- often meningiomas
- need surgery to remove
- raised ICP
- can erode skull
