ICD-10: G00
Meningitis is inflammation of the meninges. It can be caused by viruses, bacteria, or other microorganisms, but can also occur due to noninfectious stimuli.
Post-traumatic meningitis
Post-traumatic meningitis occurs in 1-20 % of patients with a moderate to severe Traumatic brain injury[^2]. In most cases, post-traumatic meningitis occurs within 2 weeks after the trauma, but in individual cases it may also occur later. In 75 % of patients with post-traumatic meningitis, fractures of the Skull base are present, and in 58 % a traumatic Cerebrospinal fluid leak is present[^3].
Chronic meningitis
Chronic meningitis is usually caused by tuberculosis, a fungal infection, or Neurocysticercosis. Sarcoidosis or meningeal carcinomatosis may be considered in the differential diagnosis[^1].
Iatrogenic meningitis
Meningitis can develop as a complication after spinal or cranial procedures, or even after minor procedures such as Lumbar drains[^4], Lumbar punctures[^5], or Myelograms[^6].
Tuberculous meningitis
Tuberculous meningitis is an infectious inflammation of the meninges that may occur during the secondary stage of tuberculosis. Typically, the basal regions of the brain are affected, as is the female patient.
