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 growth 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]
Causes
Life Threatening Causes
Considering the location of the infection the rapid progress it might have, as well as the structures affected, subdural empyema is considered a life-threatening entity in itself. Therefore, any of the causative agents and situations that may lead to the development of a subdural empyema should be considered life-theratening causes.
Common Causes
Adults
The most common cause of subdural empyema in adults is the complication of an infection of the air sinuses: frontal, ethmoid, sphenoid and maxillary. The causative organisms of the empyema will be similar to those causing the infection of the sinuses, as well as other possible causes, such as epidural abscess and brain abscess. Generally multiple organisms are present in the empyema, where anaerobes are almost always an important agent. [2][4]
- Common causative agents:
- Anaerobes
- Aerobic Streptococci
- Staphylococci
- Haemophilus influenzae
- Streptococcus pneumoniae
- Other gram-negative bacilli
- Common causative agents from sinusitis:
- Anaerobes
- Streptococcus milleri
- Streptococcus anginosus
- Staphylococcus aureus
- Streptococci
Children
The most common cause of subdural empyema in children is the complication of meningitis. The agents isolated from the pus are usually similar to the ones causing meningitis. [2][5]
- Common causative agents:
- Haemophilus influenzae
- Streptococcus pneumoniae
- Nontyphoidal Salmonella
Adults and Children
- Common causative agents in trauma:
- Coagulase negative strains of Staphylococcus
- Anaerobes
- Gram negative organisms (Campylobacter fetus)
- Common causative agents in neurosurgical procedures:
- Pseudomonas aeruginosa
- Clostridium organisms
