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] Depending on the site of origin of the infection, as well as location of the empyema in the subdural space, there will be different causative agents. The rate of success of bacterial cultures from the surgically removed pus is 54-81%. Common agents of subdural empyema include: anaerobes, aerobic streptococci, staphylococci, Haemophilus influenzae, Streptococcus pneumoniae and other gram-negative bacilli. [1] In children, subdural empyema most often happens as a complication of meningitis while in adults it usually occurs as a complication of sinusitis, otitis media, mastoiditis trauma or as a complication of neurological procedures.[1][3]
