    Summary
    This summary is machine-generated.

    Computed tomography (CT) scans accurately diagnose subdural empyema, improving patient survival rates. Early CT detection of subdural empyema leads to timely intervention and better prognoses.

    Area of Science:

    • Neurology
    • Radiology
    • Neurosurgery

    Background:

    • Subdural empyema is a serious intracranial infection.
    • Historically, mortality rates for subdural empyema were high.

    Purpose of the Study:

    • To evaluate the utility of CT scans in diagnosing subdural empyema.
    • To assess the impact of CT on patient outcomes.

    Main Methods:

    • Retrospective analysis of CT scans from 49 patients with surgically confirmed subdural empyema.
    • Evaluation of CT findings including lesion characteristics, enhancement patterns, and mass effect.

    Main Results:

    • CT scans revealed characteristic crescentic or lentiform hypodense collections with rim enhancement.
    • Mass effect was consistently present, sometimes obscuring the empyema.

  • CT enabled precise localization, including interhemispheric involvement.
  • Mortality decreased from 40% to 12% with CT-guided diagnosis and intervention.

    • Conclusions:

    • CT scanning is a crucial tool for the early and accurate diagnosis of subdural empyema.
    • Improved diagnostic capabilities via CT have significantly reduced mortality rates.
    • Specific CT findings, such as adjacent parenchymal involvement, indicate a poorer prognosis.
