What is cerebral empyema?

Intracranial subdural empyema is a loculated collection of pus in the subdural space between the dura mater and the arachnoid. It is a serious condition and can lead to significant morbidity and mortality.

Can pneumonia cause cerebral abscess?

The most common infections known to cause brain abscesses are: endocarditis, an infection of the heart valve. pneumonia, bronchiectasis, and other lung infections and conditions.

What causes Cerebritis?

Cerebritis (or myelitis) develops with bacterial and fungal infections and may be secondary to meningitis, penetrating injury, or hematogeneous dissemination from systemic infection. Small collections of acute inflammatory cells indicate the start of a bacterial abscess (Fig.

Can a brain infection be cured?

Unfortunately, there is no specific treatment for this type of viral infection.

How long does it take to recover from a brain infection?

Recovery. The inflammation of the brain can last from a few days to two or three months. After this, most people find that they make their best recovery from their symptoms within two or three months.

Does cerebritis enhance on MRI?

Because it is unusual for patients to present at this stage of cerebral infection, imaging of early cerebritis has not been reported widely. On T1-weighted MR images, an ill-defined area of isointensity or hypointensity and subtle mass effect may be seen, and contrast enhancement is absent or minimal.

How is cerebritis treated?

Usually the drug regimen included penicillin and chloramphenicol and, more recently, the combination of penicillin and metronidazole. One of the two patients with brain abscess treated with antimicrobial agents alone died. Two patients with presumed bacterial cerebritis improved with chemotherapy alone.

How does the subdural empyema affect the brain?

With progression, subdural empyema has a tendency to behave like an expanding mass lesion with associated increased intracranial pressure and cerebral intraparenchymal penetration.

What causes an empyema in the spinal canal?

The empyema may develop intracranially or in the spinal canal. Intracranial subdural empyema is most frequently a complication of sinusitis or, less frequently, otitis or neurosurgical procedures. Spinal subdural empyema is rare and may result from hematogenous infection or spread of infection from osteomyelitis.

Which is the best test for subdural empyema?

The diagnostic procedure of choice for intracranial and spinal subdural empyema is MRI with gadolinium enhancement. Computed tomography scan may miss intracranial subdural empyemas detectable by MRI. Conversely, occasion spinal subdural empyemas may be detected by CT myelography where MRI is negative.

How is subdural empyema treated in an infant?

In infants subdural puncture provides an abscess specimen for identification of the organism. Subdural puncture also drains much of the abscess. The treatment of subdural or epidural empyema requires corticosteroids to decrease ICP, antimicrobials to eradicate the organisms, and anticonvulsants for seizures.
