The meninges comprise three membranes that, together with the cerebrospinal fluid, enclose and protect the brain and spinal cord (the central nervous system). The pia mater is a delicate impermeable membrane that firmly adheres to the surface of the brain, following all the minor contours.
The SLYM is located in the subarachnoid space, the space between the middle reticular meninges and the innermost tender meninges that lie close to the brain. [10] It divides the subarachnoid space into an outer, superficial compartment and an inner, deeper area surrounding the brain. [10]
MRI of the brain with contrast may show enhancement of the meninges and the subarachnoid space however MRI may also be normal. [ 6 ] [ 2 ] MRI is the preferred neuroimaging test to diagnose chronic meningitis, being more sensitive than CT of the brain, however, MRI scanners are not available in many resource-limited settings where chronic ...
Meningism is a set of symptoms similar to those of meningitis but not caused by meningitis. [1] [3] [4] Whereas meningitis is inflammation of the meninges (membranes that cover the central nervous system), meningism is caused by nonmeningitic irritation of the meninges, usually associated with acute febrile illness, [1] [2] especially in children and adolescents. [2]
The arachnoid mater is interposed between the two other meninges, the more superficial (closer to the surface) and much thicker dura mater and the deeper pia mater, from which it is separated by the subarachnoid space. The delicate arachnoid layer is not attached to the inside of the dura but against it, and surrounds the brain and spinal cord.

Mycobacterium tuberculosis of the meninges is the cardinal feature and the inflammation is concentrated towards the base of the brain. [6] When the inflammation is in the brain stem subarachnoid area, cranial nerve roots may be affected. The symptoms will mimic those of space-occupying lesions. [7]
The subarachnoid cisterns are spaces formed by openings in the subarachnoid space, an anatomic space in the meninges of the brain. [1] The space is situated between the two meninges, the arachnoid mater and the pia mater. These cisterns are filled with cerebrospinal fluid (CSF). [1]
