MRI of Emergent Intracranial Infections and Their Complications

Area of Science:

• Neuroradiology
• Infectious Diseases
• Emergency Medicine

Background:

• Acute intracranial infections are rare but critical diagnoses.
• Nonspecific symptoms can delay diagnosis, necessitating a high index of suspicion.
• Imaging is crucial for diagnosis, characterization, and exclusion of other conditions.

Purpose of the Study:

• To review key imaging findings of acute intracranial infections.
• To highlight the role of imaging in emergent settings.
• To compare the utility of different imaging modalities.

Main Methods:

• Review of typical and critical imaging manifestations.
• Focus on emergent diagnostic scenarios.
• Comparison of computed tomography (CT) and magnetic resonance imaging (MRI) findings.

Main Results:

• MRI demonstrates superior sensitivity and specificity for intracranial infections compared to CT.
• Imaging is essential for defining the extent of infection and identifying complications.
• Characteristic imaging findings aid in timely diagnosis.

Conclusions:

• Prompt recognition of intracranial infections is vital.
• MRI is the preferred modality for detailed evaluation of intracranial infections.
• Understanding imaging features is critical for emergency department management.
