title: Delayed endolymphatic hydrops: a case study.
abstract: Delayed endolymphatic hydrops (DEH) is an unusual variation of Ménière's disease characterized by episodic vertigo that develops some time after the onset of a profound, typically unilateral sensorineural hearing loss. This case study describes a 48-year-old male who presented with complaints of episodic vertigo and disequilibrium 15 years following the onset of unilateral sensorineural hearing loss. The patient's history, audiologic findings, and vestibular evaluation led to the diagnosis of DEH. The case highlights the diagnostic and treatment challenges associated with this condition and focuses attention on principles that guide the audiologist in collecting evidence that aids in solving these challenges.
