Abstract:
We report a 45-year old male who developed subdural empyema (SE) with tension pneumocephalus. The patient was admitted unconscious with tonic extensor response to pain. A "gas-forming" organism, Escherichia coli, was detected. Surgical evacuation of the pus and treatment with the appropriate antibiotic did not result in amelioration of his symptoms and the patient died. We identified a rare clinical situation when the SE cavity had a relatively large air loculus that was clearly related to gas-forming bacteria. It appeared that the patient had developed tension pneumocephalus related to the air produced by the pathogen. To our knowledge, this is the first report of a gas-forming organism in an abscess cavity that resulted in tension pneumocephalus and related symptoms.
Insights
A rare case of subdural empyema caused by gas-forming Escherichia coli led to tension pneumocephalus. This unusual bacterial infection resulted in fatal neurological complications despite treatment.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Subdural empyema (SE) is a serious intracranial infection.
- Tension pneumocephalus is a rare but life-threatening complication of SE.
Observation:
- A 45-year-old male presented with unconsciousness and extensor posturing.
- Escherichia coli, a gas-forming bacterium, was identified as the causative agent of SE.
- A large air loculus within the SE cavity was noted, linked to bacterial gas production.
Findings:
- The patient developed tension pneumocephalus secondary to gas produced by E. coli within the subdural empyema.
- Despite surgical intervention and antibiotics, the patient's condition deteriorated, leading to death.
Implications:
- This case highlights a novel mechanism of tension pneumocephalus in subdural empyema.
- The presence of gas-forming organisms in SE requires careful consideration for potential pneumocephalus development.
- This report underscores the critical need for prompt diagnosis and management of SE, especially when complicated by gas-producing pathogens.
