Imaging of Vertigo and Dizziness: A Site-based Approach Part 3 (Brainstem, Cerebellum, and Miscellaneous).

Abstract

Dizziness and vertigo, frequently associated with cerebrovascular origins, pose a substantial challenge in emergency medical settings due to their potential to be associated with severe underlying conditions. Sudden-onset dizziness, in particular, may be an early indicator of critical events such as stroke or transient ischemic attack. This comprehensive review encompasses the differential diagnosis of central causes of dizziness and vertigo, emphasizing the crucial role of imaging modalities in the accurate detection and assessment, including cerebrovascular diseases, inflammatory disorders, infections, and other conditions such as vestibular migraine and cervical spondylosis. It highlights the significance of advanced imaging techniques, particularly magnetic resonance imaging and computed tomography in identifying and distinguishing these conditions.
