Ménière's disease (MD) is a relatively common and debilitating ear disorder characterized by repetitive episodes of vertigo, fluctuating sensorineural hearing loss (SNHL), tinnitus, and ear swelling
Ménière's disease (MD) is a relatively common and debilitating ear disorder characterized by repetitive episodes of vertigo, fluctuating sensorineural hearing loss (SNHL), tinnitus, and ear swelling
Delayed endolymphedema (DEH), another rarer subtype, is characterized by late-onset episodic vertigo after severe SNHL, with ear symptoms similar to MD
A study published in the journal European Radiology reviewed MRI assessments of patients with ipsilateral DEH and unilateral MD, and explored differences in anatomical changes in inner ear MRI between these two disorders, as well as the correlation of imaging findings with clinical features or auditory outcomes.
A total of 28 patients with ipsilateral DEH, 76 patients with unilateral MD, and 59 controls were included in this study
(1) The MRI-PP distance of the affected side of unilateral MD was shorter than that of ipsilateral DEH (Z=-2.

Differences in MRI visualization measures between ipsilateral DEH and unilateral MD suggest that anatomical changes in the endolymphatic sac may be a predisposing factor in the pathogenesis of unilateral MD but not ipsilateral DEH
