Depending on the underlying infection, the way it entered the brain, and the type and timing of treatment, the infection may spread or withdraw on the order of months or days. Ventriculitis is a very serious condition and should be treated early to ensure as little lasting damage as possible.
The EVD is a foreign body inserted into the brain, and as such it represents a potential portal for serious infection. Historically, the rate of infections associated with EVDs has been very high, ranging from 5% to > 20%. [10] [11] Infections associated with EVDs can progress to become a severe form of brain infection known as ventriculitis.
Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
Infections of the central nervous system (CNS) consist of infections primarily of the brain and spinal cord. They include mostly viral infections, less commonly bacterial infections, fungal infections, prion diseases and protozoan infections. Neonatal meningitis is a particular classification by age.
Infection is a common complication that normally affects pediatric patients because they have not yet built up immunities to a number of different diseases. Normally, the incidence of infection decreases as the patient grows older and the body gains immunity to various infectious agents. [10] Shunt infection can occur in up to 27% of patients.
It typically occurs about 6–7 years after initial infection and it may affect those with early disease. It may present as stroke or spinal cord infarct. Signs and symptoms vary with vascular territory involved. The middle cerebral artery is most often affected. [7] Parenchymal syphilis occurs years to decades after initial infection.
Two years after taking the pills, an MRI showed that he had a ruptured bicep tendon which required surgery to reattach it. "I just got up one morning with a very painful shoulder," he said.
Brain scan, done by MRI, can determine inflammation and differentiate from other possible causes. EEG , in monitoring brain activity, encephalitis will produce abnormal signal. Lumbar puncture (spinal tap), this helps determine via a test using the cerebral-spinal fluid, obtained from the lumbar region.
