Introduction: The benign nature of Bell’s palsy has led to a lack of a standardized work-up, and dangerous underlying mimics are at risk of being missed. Case
Report: An 84-year-old female with a history of vertigo presented to the emergency department with a left-sided facial droop consistent with Bell’s palsy. After further work-up, the patient was diagnosed with bilateral necrotizing mastoiditis.
Conclusion: Unilateral facial weakness involving the forehead and palpebral fissures is often diagnosed as idiopathic Bell’s palsy. Various pathologies can present with unilateral facial weakness, and the differential needs to remain broad.
