It can occur at any age, and it constitutes an emergency, since it may cause a mortality rate between 2 and 30 % or lead to permanent sequela as: brain edema, cerebral infarction, cranial nerve paralysis, neuroendocrine disorders, intracranial collections or hypertension, neurosensorial deafness, psychomotor delay, and cerebral palsy. According to the length of its evolution it is classified in acute, chronic and recurrent; according to its etiology, in infectious and non infectious. Infectious etiologies are viral, bacterial, fungic and parasitic. Non infectious etiologies are tumoral, toxic and systemic diseases. Infectious agents that invade the Central Nervous System (CNS) may cause meningitis by three mechanisms: first they colonize and infect the guest via skin, respiratory, genitourinary or gastrointestinal systems. They invade the submucosa, overcome the guest’s physical and immune barriers, and penetrate the CNS through 3 routes: blood, neuronal retrograde access and direct inoculation. Keywords Meningitis, Central Nervous System, inflammation, emergency, sequelae.
