During the course of our lives we are subject to many different threats, among them, viral or infectious diseases. Infections can develop anywhere in our body, including our brain. The most common types of brain infections are known as brain abscesses. Most cases are serious and require surgery. Undoubtedly, in such cases we would try to find the best neurosurgeon in Spain to perform the operation successfully.

A brain abscess occurs as a result of accumulation of pus inside the brain. Infections generate pus and can occur at any age. In addition, this abscess may be single or multiple, that is to say, one or many in different parts of the brain. First, the brain suffers inflammation, known as cerebritis, and as the disease evolves, a pus filled cavity is formed, that tends to increase in size progressively.

Among the main causes of brain abscesses, we can highlight the following:

  1. Infections elsewhere in the human body (lungs, bones, skin, etc.) which can spread via the blood, reach the brain and cause an abscess.
  2. Severe head injuries with deep open wounds can also cause brain abscesses.
  3. However, the most frequent cause is a localized infection in the head region. For example, uncontrolled sinusitis, and ear or mouth infections.

The most common symptoms are those of an infection: fever, malaise, fatigue, etc. As these abscesses are an internal mass located in the brain, they can cause other problems such as headaches, nausea, speech difficulties or loss of limb movements, symptoms that can last up to several weeks.

At Instituto Clavel, we wish to emphasize the importance of a quick diagnosis in order to act immediately to eliminate these abscesses. The best way to detect them is by means of a cranial CT scan or a MRI scan. It is always advisable to consult a skilled professional, as these brain abscesses are not easily seen and can be confused with other conditions such as brain tumors.
