Abscess of the brain
Brain abscess is a significant accumulation of pus in the brain, which occurs again in the presence of focal infection outside the central nervous system. Perhaps the simultaneous existence of several abscesses, depending on their size and quantity, is more or less affected by the brain. Symptoms of this lesion are different, for example, paralysis, impaired sensitivity or orientation. Epilepsy may occur. In addition, there are general symptoms of the disease, for example, fever, headache, nausea and vomiting. The formation of a foci of infection is often accompanied by inflammation of the brain.

Depending on the way the infection gets into the brain, the following types of abscesses are divided:

  • Traumatic - occur after head injuries, accompanied by bleeding and the entry of pathogens into the wound.
  • Postoperative - the consequence of the infiltration of infectious agents into the wound during the operation or in the process of rehabilitation.
  • Ottogenous - after the development of complications of infectious diseases of the ear.
  • Rinogenous - as a result of infectious diseases of the nose and nasal sinuses, the infection can spread to other organs, including the brain.
  • Hematogenous - the spread of infection with blood flow.
  • Metastatic - infection from other organs and systems.

Symptoms

  • Violation of sensitivity and speech.
  • Epileptic seizures.
  • Headache, nausea, vomiting.
  • Photophobia.
  • Temperature increase.
  • Paralysis.

Causes

Usually, cerebral abscess occurs when a bacterial infection penetrates. Pus from the abscess consists of leukocytes, which try to destroy bacteria, their remains, dead tissues and a host of different microbes. The human body reliably protects the brain from the penetration of bacteria. However, in chronic, long-lasting infections, bacteria enter the bloodstream. With blood flow, they can easily get into the brain, as a result of this process, a purulent focus is formed. Also, dangerous bacteria can penetrate into the skull when receiving open craniocerebral injuries. Another way of spreading the infection is purulent otitis and a purulent infection of the paranasal sinuses, as well as various abscesses on the skin of the upper half of the face.

Treatment

Symptoms of abscess are usually nonspecific. However, general symptoms, such as an intensifying headache, nausea and vomiting, are always alarming, so when they appear, you need to see a doctor.

First of all, a blood test is performed, which will establish a presumptive diagnosis. To confirm the diagnosis, a CT scan of the brain is necessary.

At the initial stage of the inflammatory process, an attempt is made to treat antibacterial and anti-inflammatory drugs. If time for drug therapy is missed or there is no improvement, surgical intervention is necessary. The body is usually alone unable to cope with the disease, even with the help of strong antibiotics. The complexity and danger of such neurosurgical operations depends on the localization of the abscess. In the case of deeply located abcesses of the brain or abscesses of functionally significant areas, puncture aspiration followed by the introduction of antibacterial drugs is considered the only method of treatment.

With this disease, independent treatment is unacceptable, you should consult a doctor and strictly follow his instructions.

Effects

Brain abscess is a very serious and serious disease characterized by residual phenomena even after recovery of the patient. In connection with the gradual increase in the abscess, over time there is a strong squeezing of the brain in the skull, resulting in a violation of its functions and the patient dies. However, with the timely and successful removal of the abscess, the patient can recover. Especially important is the timely treatment of major diseases that contribute to the emergence of an abscess.

To avoid infectious brain damage, timely and correct treatment of foci of infection arising during the development of various infectious diseases, for example, inflammation of the middle ear, labyrinthitis, sinusitis, sinusitis, etc., is necessary.
