Overview
Subdural empyema, also referred to as subdural abscess, pachymeningitis interna and circumscript meningitis, is a life-threatening infection, first reported in literature approximately 100 years ago.[1] It consists of a located collection of purulent material, usually unilateral, between the dura mater and the arachnoid mater. It accounts for about 15-22% of the reported focal intracranial infections. The empyema may develop intracranially (about 95%) or in the spinal canal (about 5%), and in both cases, it constitutes a medical and neurosurgical emergency.[2] The intracranial type tends to behave like an expanding mass, causing clinical symptoms, such as fever, lethargy, headache and neurological deficits. These result from the extrinsic compression of the brain, caused not only from the inflammatory mass, but also from the inflammation of the brain and meninges. Because the subdural space has no septations, except in areas where arachnoid granulations attach to the dura mater, the subdural empyema tends to speed quickly, until it finds those boundaries.
With treatment, including surgical drainage, resolution of the empyema occurs from the dural side, and, if it is complete, a thickened dura may be the only residual finding.
