Young Park MD, Presenter: Nothing to Disclose

Vinh Tuy Nguyen MD, Abstract Co-Author: Nothing to Disclose

-Review the definition of vertigo and dizziness -Review the differential diagnosis for patients presenting with these symptoms -Discuss the role of imaging in diagnosis and management of such diseases  

Review anatomy, clinical presentation, pathophysiology, and imaging findings -Inner ear: Ménière’s disease, labyrinthitis, semicircular canal dehiscence -Cranial nerve: vestibular schwannoma, leptomeningeal carcinomatosis, microvascular compression -Vertebrobasilar insufficiency, cerebrovascular disease -Demyelination -Cerebellar tumors -Skull base and craniovertebral junction: clival chordoma, meningioma Sample cases Multidisciplinary approach -Symptomatology frequently overlaps within this broad spectrum of diseases, patients cross over between different specialties -Radiologist is in central overarching role to differentiate between various etiologies and facilitate multidisciplinary approach to evaluate vertigo and dizziness 

-Vertigo and dizziness are symptoms of a broad scope of diseases affecting the vestibular system -Neuroimaging is particularly valuable in cases demonstrating neurologic signs/symptoms, cerebrovascular risk factors, or progressive unilateral hearing loss -Frequent overlap in symptomatology necessitates multidisciplinary approach towards diagnosis and management of these patients
