Podcast 523: A Dizzying Diagnosis

Contributor: Don Stader, MD

Educational Pearls:

• It can be difficult to distinguish between central and peripheral causes of vertigo. Cerebellar stroke should be considered with any dizzy patient.
• Signs and symptoms that suggest stroke as the cause of vertigo include: ataxia, cranial nerve deficits, and rapid onset of symptoms
• When cerebellar stroke is being considered, MRI is the imaging modality of choice since CT does not adequately visualize the posterior fossa.
