Otogenic intracranial abscesses
1Clinic of Neurosurgery, Dicle University School of Medicine, Diyarbakir, Turkey.
Abstract:
The commonest cause of the intracranial abscesses collected prospectively during the last two years was chronic middle ear infection (73%). The diagnosis was based on the clinical history, otological investigations, contrast enhanced computerized tomography and surgical findings. The clinical presentation was characterized by chronic otitis with an exacerbation of otorrhea, otalgia or pain in the temporal region or headache with high fever, vomiting and nausea. A review of our 14 patients with otogenic intracranial abscesses is reported to highlight that prompt diagnosis, appropriate therapy and careful monitoring can provide vastly improved results.
Insights
Chronic middle ear infections are the leading cause of intracranial abscesses. Prompt diagnosis and treatment of these brain abscesses, often presenting with ear issues and fever, significantly improve patient outcomes.
Area of Science:
- Neurology
- Otolaryngology
- Infectious Diseases
Background:
- Intracranial abscesses pose significant neurological risks.
- Otogenic sources, particularly chronic middle ear infections, are a common etiology.
- Understanding the clinical presentation is crucial for early detection.
Purpose of the Study:
- To identify the primary cause of intracranial abscesses in a prospective cohort.
- To describe the clinical characteristics and diagnostic methods for otogenic intracranial abscesses.
- To emphasize the importance of timely intervention and management.
Main Methods:
- Prospective data collection over two years.
- Diagnosis based on clinical history, otological evaluation, and imaging (contrast-enhanced CT).
- Analysis of surgical findings in patients with otogenic intracranial abscesses.
Main Results:
- Chronic middle ear infection identified as the most common cause (73%) of intracranial abscesses.
- Typical presentation includes chronic otitis with exacerbated symptoms like otorrhea, otalgia, headache, fever, and nausea.
- Review of 14 patients with otogenic intracranial abscesses.
Conclusions:
- Chronic otitis media is a significant risk factor for developing intracranial abscesses.
- A combination of clinical suspicion, diagnostic imaging, and surgical assessment is vital.
- Aggressive management, including prompt diagnosis and appropriate therapy, leads to better patient outcomes.
