The magnetic resonance imaging profile of occult intracranial violations as a result of sinus surgery

New-onset and/or atypical headache after sinus surgery may be associated with occult intracranial injury. MRI may serve as the diagnostic means for this occult intracranial violation. Significant incongruity may exist between patient symptoms and the objective MR evidence that can suggest serious intracranial injury. MRI signal patterns can provide both temporal and anatomical cues about the specific injury.
