Focal intracranial infections
1Temple University School of Medicine and Hospital, Philadelphia, Pennsylvania, USA.
Abstract:
Focal intracranial infections are relatively rare, but the consequences of a missed or delayed diagnosis are significant. The clinician is urged to consider these diagnoses in patients with headaches or focal neurologic examinations, particularly in the setting of known or suspected otorhinologic disease. For diagnosis, gadolinium-enhanced MR imaging or MR imaging with angiography are the procedures of choice; CT is far less sensitive and specific. Lumbar puncture is contraindicated in most of these infections. Management of suspected elevation of intracranial pressure and broad empiric antibiotic therapy should be instituted emergently. Early involvement of surgical services is recommended.
Insights
Prompt diagnosis of focal intracranial infections is crucial due to severe consequences. Clinicians should consider these infections in patients with headaches or focal neurological deficits, especially with otorhinologic disease.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Focal intracranial infections are uncommon but can lead to severe outcomes if diagnosis is delayed.
- Headaches and focal neurological deficits warrant consideration for intracranial infections, particularly with concurrent otorhinologic conditions.
Purpose of the Study:
- To highlight the importance of early recognition and diagnosis of focal intracranial infections.
- To outline appropriate diagnostic and management strategies for these rare but serious conditions.
Main Methods:
- Review of clinical presentations and diagnostic modalities for focal intracranial infections.
- Emphasis on advanced neuroimaging techniques and contraindications for lumbar puncture.
Main Results:
- Gadolinium-enhanced MRI or MR angiography are the preferred diagnostic tools.
- CT scans are less sensitive and specific compared to MRI.
- Lumbar puncture is generally contraindicated due to risks associated with intracranial pressure elevation.
Conclusions:
- Prompt diagnosis and management of focal intracranial infections are critical.
- Early initiation of broad-spectrum antibiotics and management of intracranial pressure are essential.
- Early consultation with surgical services is recommended for optimal patient outcomes.
