The cost of treating intracranial infections is, in general, high. Intracranial infections are more commonly non-specific infections, mainly purulent meningitis. If a patient has purulent meningitis, a lumbar puncture procedure and cerebrospinal fluid laboratory tests are inevitably performed. Cerebrospinal fluid laboratory tests mainly include cerebrospinal fluid routine, cerebrospinal fluid biochemistry, as well as cerebrospinal fluid culture and drug sensitization tests. Based on the specific results, the appropriate effective medication is selected. Generally, ceftriaxone (Rocephin) is more effective. Such medication will take a total of four weeks, and the cost of medication alone may be around 30,000 dollars. If the patient has caused a brain abscess, he or she will also have to undergo a brain abscess puncture and aspiration procedure or a craniotomy, and the cost of such a procedure will be about$50,000 or so. If the patient has a specific intracranial infection, such as tuberculous meningitis, the entire treatment cycle is about one and a half years, and the total cost may be more than 100,000 yuan.
