[SENSORINEURAL HEARING LOSS AND VERTIGO DUE TO INTRA-COCHLEAR HEMORRHAGE].

INTRODUCTION

Intra-cochlear hemorrhage is a rare cause of sudden sensorineural hearing loss (SSNHL) which may be accompanied by diverse labyrinthine symptoms. In these cases, we expect magnetic resonance imaging (MRI) to demonstrate a high signal intensity in the labyrinth on unenhanced T1-weighted images as well as in fluid-attenuated inversion recovery (FLAIR) images.

AIMS: To describe an experience with a case of intra-cochlear hemorrhage in a patient treated with anticoagulation, causing SSNHL and vertigo.

METHODS

Case report and literature review.

RESULTS

An 85-year old patient treated with anticoagulation therapy presented with right SSNHL, tinnitus and vertigo. Physical examination revealed: bilateral normal otoscopic examination, lateralized left Weber tuning fork test and a spontaneous left horizontal nystagmus. MRI performed demonstrated a high signal intensity inside the cochlea on unenhanced T1-weighted images.

CONCLUSIONS

Performing an MRI is necessary in order to rule out frequent causes of SSNHL including benign as well as malignant tumors, malformations, trauma and more. The finding of an intra-labyrinthine hemorrhage causing SSNHL is rare, and should be taken into consideration when treated by anticoagulation therapy.
