Concurrent Pathologies of Endolymphatic Hydrops and Perilymphatic Fistula.

Ménière's disease (MD) and perilymphatic fistula (PLF) are considered to develop independently, with different etiologies.

Here, we present the first case, to our knowledge, of fluctuating hearing loss and recurrent vertigo episodes in which both concurrent EH and PLF were detected, using new diagnostic tools.
