What are the clinical signs and imaging tests for intracranial parameningeal infections?

The suspicion of intracranial septic thrombophlebitis should be considered in any patient with central neurological symptoms of infectious origin and a history of infection in some adjacent anatomical structure.
The initial evaluation should include a complete neurological examination, with special attention to assessing the level of consciousness, cranial nerves, sensory and motor deficits, neck stiffness, and signs suggestive of intracranial hypertension.
Intracranial parameningeal infections are a medical-surgical emergency and require immediate empirical broad-spectrum antibiotic therapy, antipyretics, and neurosurgical evacuation, with the treatment of the initial cause being fundamental.
