Abstract
We examined a 61-year-old woman with sudden left-side hearing loss accompanied by severe vertigo. High signal in the ampullar endolymph of the left semicircular canal on magnetic resonance (MR) fluid attenuated inversion recovery (3D-FLAIR) images suggested labyrinthine hemorrhage. The patient had been treated for chronic heart failure and prescribed 100 mg/day of acetylsalicylic acid (aspirin) for its antiplatelet effect. The 3D-FLAIR images demonstrated a small amount of focal hemorrhage in the labyrinthine fluid that may have been overlooked on T(1)-weighted images.
