The management of cerebellar abscess since the introduction of CT scanning
1Department of Neurosurgery, Queen Elizabeth Hospital, Birmingham, UK.
Abstract:
Sixteen patients with surgical infection of the posterior fossa are presented. There were 14 patients with cerebellar abscess, one patient with a solitary posterior fossa subdural empyema, and another with a combined cerebellar abscess and subdural empyema. Two of the cerebellar abscess patients also had supratentorial infections. The presenting features, aetiology, radiology and bacteriology are discussed with particular reference to differences in abscess re-accumulation, and outcome between those managed by aspiration and excision. We have been unable to show that either method of treatment is superior to the other. An overall mortality rate of 19% was achieved; however, for those with parenchymal cerebellar abscesses this was reduced to 13%. We conclude that burr hole aspiration with regular CT is a satisfactory method of treatment for cerebellar abscess.
Insights
Surgical posterior fossa infections, including cerebellar abscesses, were treated with aspiration or excision. Both methods showed similar outcomes, with burr hole aspiration and CT scans proving effective for cerebellar abscess management.
Area of Science:
- Neurosurgery
- Infectious Diseases
Background:
- Posterior fossa surgical infections are serious conditions.
- Cerebellar abscesses and subdural empyemas present significant management challenges.
Purpose of the Study:
- To analyze the clinical features, etiology, and outcomes of posterior fossa infections.
- To compare the efficacy of aspiration versus excision in treating cerebellar abscesses.
Main Methods:
- Retrospective review of 16 patients with posterior fossa surgical infections.
- Analysis of presenting features, etiology, radiology, and bacteriology.
- Comparison of treatment outcomes between aspiration and excision methods.
Main Results:
- 14 patients had cerebellar abscesses, one subdural empyema, and one combined infection.
- No significant difference in outcomes was found between aspiration and excision.
- Overall mortality was 19%, reduced to 13% for parenchymal cerebellar abscesses.
Conclusions:
- Burr hole aspiration with regular CT monitoring is a satisfactory treatment for cerebellar abscess.
- Both aspiration and excision are viable treatment options for posterior fossa infections.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
