Meningitis can be detected by physical examination, laboratory tests, and imaging tests.
1. Physical examination: Meningitis is a diffuse inflammatory change in the soft meninges. Meningitis can be detected by physical examination, such as fever, chills, meningeal irritation, headache and limb disorder.
2. Laboratory tests: such as elevated white blood cells, elevated ultrasensitive C-reactive protein, viral meningitis can also be found positive for viral antibodies.
3. Imaging examination: such as tuberculous meningitis will appear plum-like bead-like high density shadow, bacterial meningitis will appear cerebral edema and occupancy, new cryptococcal meningitis will appear perivascular gap dilatation and so on.
When meningitis is suspected, it is necessary to consult a doctor in time for examination, and actively treat under the doctor’s guidance after the diagnosis is confirmed, so as to avoid aggravation of the condition.
