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.
