Abstract
Evaluation of patients with cranial neuropathies requires an understanding of brainstem
anatomy and nerve pathways. Advances in neuroimaging, particularly high spatial resolution
magnetic resonance imaging (MRI), have enabled visualization of these tiny structures
and their related pathology. This review provides an approach toward using imaging
in the evaluation of cranial nerve (CN) and skull base anatomy and pathology. Because
brainstem nuclei are inextricably linked to the information contained within CNs,
they are briefly mentioned whenever relevant; however, a comprehensive discussion
of brainstem syndromes is beyond the scope of this review.
