Figure 2.
Morphology of the ED-ES complex on axial contrast-enhanced FLAIR images. The visibility of the ED-ES system was evaluated from the posteromedial aspect of the vestibule to the opercular region. (A) Normal visualization of the ED-ES system (long arrow) in a patient diagnosed with vestibular migraine. (B) Non-visualization of the ED-ES system in patient with definite MD. (C, D) Corresponding schematic depiction of the MR images. The visible parts of the cochlea, vestibule, and semicircular canals are depicted in orange. In (C), the saccule and utricle are depicted in blue and green, respectively. Note the presence of vestibular hydrops (depicted in blue) in (D).
