Abstract:
Intracranial dural empyema is a neurosurgical emergency with potentially devastating complications. The prognosis is adversely affected by delay in diagnosis. Modern imaging techniques, especially contrast enhanced CT and MRI, have improved the speed and accuracy of radiological diagnosis of this condition, with an associated reduction in mortality. Despite this, there may still be a delay in diagnosis, partly owing to the subtlety of early radiological signs, especially on unenhanced CT. We present cases that illustrate some of the radiological manifestations, complications and potential pitfalls in diagnosis.
Insights
Intracranial dural empyema is a serious neurosurgical condition. Prompt diagnosis using advanced imaging like CT and MRI is crucial to reduce complications and improve patient outcomes.
Area of Science:

- Radiology
- Infectious Diseases
Background:
- Intracranial dural empyema presents a critical neurosurgical emergency.
- Delayed diagnosis significantly worsens patient prognosis and increases complication risks.
- While advanced imaging aids diagnosis, subtle early signs on unenhanced CT can cause delays.
Purpose of the Study:
- To illustrate the radiological manifestations of intracranial dural empyema.
- To highlight common complications associated with this condition.
- To identify potential diagnostic pitfalls in radiological interpretation.
Main Methods:
- Case series presentation.
- Review of radiological findings from contrast-enhanced CT and MRI.
- Analysis of diagnostic challenges and delays.
Main Results:
- Demonstration of diverse radiological signs of dural empyema.
- Identification of complications such as abscess formation and venous sinus thrombosis.
- Examples of subtle early signs and interpretation errors on imaging.
