Antibiotics are the first-line treatment for brain abscess. High-dose, broad-spectrum, intravenous antibiotics should be administered as early as possible in the patient's course. Emergent consultation with neurosurgery is recommended; however, delay in consultation should not delay antibiotic administration.
Treat all brain abscesses with antibiotics (usually initially with ceftriaxone or cefotaxime plus metronidazole if clinicians suspect Bacteroides species or plus vancomycin if they suspect S. aureus), typically followed by CT-guided stereotactic aspiration or surgical drainage.
It should be covered with vancomycin. It is also effective for Clostridium species. In cases of vancomycin resistance, linezolid, trimethoprim-sulfamethoxazole, or daptomycin can be considered. Fungal infections including Candida, Cryptococcus needs to be treated with Amphotericin B.
Your healthcare provider can treat cerebral abscesses with medicines, including antibiotics or drugs to fight a fungal infection. Your healthcare provider may also give you steroid drugs to lower pressure in your brain, or other drugs to reduce seizures. You may need surgery, especially for larger abscesses.
Most common symptoms
Because these can be symptoms of many illnesses, a brain abscess can be hard to detect at first. In two-thirds of cases, people have symptoms for as long as two weeks before they are diagnosed.
A brain abscess is usually caused by infection with either bacteria or fungi. If the immune system is unable to kill an infection, it will try to limit its spread by using healthy tissue to form an abscess, to stop the pus infecting other tissue.
A brain abscess is regarded as a medical emergency. Swelling caused by the abscess can disrupt the blood and oxygen supply to the brain. There's also a risk of the abscess bursting (rupturing). If left untreated, a brain abscess can cause permanent brain damage and could be fatal.
A brain abscess can grow very quickly, typically becoming fully formed within about two weeks. Your doctor will begin treatment immediately after you are diagnosed. Prompt medical attention is the key to relieving your symptoms more quickly and minimizing damage to your long-term health.
The advised standard treatment for bacterial brain abscess following surgery is 6 to 8 weeks of intravenous (IV) antibiotic treatment, but an early switch to oral antibiotic treatment has been suggested to be equally effective.
Intracranial abscesses are uncommon, serious, life-threatening infections. They include brain abscess and subdural or extradural empyema and are classified according to the anatomical location or the etiologic agent. The term brain abscess is used in this article to represent all types of intracranial abscesses.
Brain abscess passes through 4 stages: early cerebritis, late cerebritis, early capsule, and late capsule. During early cerebritis, nonenhanced CT scans may demonstrate normal findings or may show only poorly marginated subcortical hypodense areas.
In most modern series, the mortality rate is typically less than 15%. Rupture of a brain abscess is uncommon but is associated with a high mortality rate (up to 80%). Significant morbidity, including seizures, persistent weakness, aphasia, or cognitive impairment, affects an estimated at 20-30% of survivors.
Background. The advised standard treatment for bacterial brain abscess following surgery is 6 to 8 weeks of intravenous (IV) antibiotic treatment, but an early switch to oral antibiotic treatment has been suggested to be equally effective.
Most people can go back to work or their normal routine 1 or 2 days after surgery. It will probably take about 3 to 8 weeks for the abscess to completely heal. Most people get better without any problems.
What Are the Symptoms of a Brain Abscess? The most common symptoms are fever, headache, and nervous system problems. Such problems may be confusion, disorientation, speech or walking difficulties, change in mental status, or arm and leg weakness on one side.
Abscess occurs most commonly in the frontal lobe but may occur in any location. Location is closely associated with source. Otogenic abscess occurs almost exclusively in the temporal lobe and cerebellum, while abscess associated with sinus infection is predominantly frontal.
Antimicrobial treatment for a brain abscess is generally long (6-8 wk) because of the prolonged time needed for brain tissue to repair and close abscess space. The United Kingdom treatment guidelines advocate 4-6 weeks if the abscess has been drained or removed and 6-8 weeks if drainage occurred.
CT scan has formed the mainstay in the diagnosis of patients of brain abscess in recent years. It offers a highly accurate, relatively noninvasive and rapid means of establishing the diagnosis and following the course of disease.
For example, in the late stage of bacterial infection, the formation of brain abscess shows MRI manifestation as a typical rim-like enhancement, which is often similar to necrotic malignant tumors, especially glioblastoma multiforme (GBM) (8).
Between 1,500 and 2,500 cases occur each year in the United States. Brain abscesses are most likely to affect adult men aged under 30 years. Among children, they most commonly develop in those aged 4–7 years. Newborns are also at risk.
Prognosis. The prognosis for a brain infection depends on the severity of your condition, what caused the infection, and how fast treatment was initiated. Most people who experience a brain infection make a full recovery.
The severity of viral encephalitis depends on the particular virus and how quickly treatment was given. Generally, the acute phase of the illness lasts around one or 2 weeks, and the symptoms either disappear quickly or subside slowly over a period of time. In many cases, the person makes a full recovery.
Unlike other infections, antibiotics alone will not usually cure an abscess. In general an abscess must open and drain in order for it to improve. Sometimes draining occurs on its own, but generally it must be opened with the help of a warm compress or by a doctor in a procedure called incision and drainage (I&D).
IV antibiotics are antibiotics that are administered directly into a vein to enter the bloodstream immediately and bypass the absorption in the gut. This delivery method is used for severe infections like sepsis because intravenous antibiotics reach tissues faster and at higher concentrations than oral antibiotics.
Complete resolution of abscess with complete recovery of preoperative neuro-deficit was seen in 80.86% cases and recovery with major neuro-deficit was observed in 5.55% cases.
