Diagn Interv Radiol. 2009 Dec;15(4):239-41. doi: 10.4261/1305-3825.DIR.1621-08.1. Epub 2009 Oct 27.

Abstract

Labyrinthitis ossificans is fibrosis or ossification of the membranous labyrinth. Tympanogenic, meningogenic, and hematogenous etiologies are more common than trauma in the development of labyrinthitis ossificans. We present a case complaining of right-sided hearing loss and symptoms of otitis media and positional vertigo resulting from perilymphatic fistulization. Imaging revealed labyrinthitis ossificans secondary to temporal bone fracture crossing through the otic capsule.
