Overview
Subdural empyema, also referred to as subdural abscess, pachymeningitis interna and circumscript meningitis, is a life-threatening infection.[1] It consists of a localised collection of purulent material, usually unilateral, between the dura mater and the arachnoid mater and 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] Bacterial or occasionally fungal infection of the skull bones or air sinuses can spread to the subdural space producing a subdural empyema.
Epidemiology
Rare disorder accounting for 15-25% of focal CNS infections. It usually occurs in infancy and young adults (70% cases occurring in the second and third decades of life), being more frequent in men than women, possibly due to sex-related differences in sinus anatomy. It develops in 39-60% of the cases of pyogenic meningitis, but only in 1-2% of the cases of bacterial meningitis. [3][2] However sinusitis is the most common predisposing condition, typically involving the frontal air sinus alone or concomitantly with ethmoid and maxillary sinuses. Less frequent cases develop as a complication of head trauma or neurosurgical procedures.[4]
