Abstract We hereby present the case of a 32 year old patient with sudden sensorineural hearing loss (SNHL) and an MRI compatible with acute intra-cochlear hemorrhage. Spontaneous intra-labyrinthine bleeding is a rare cause of SNHL. Bleeding into the membranous labyrinth may lead to high concentrations of blood byproducts. Commonly affected subsites are the basal turn of the cochlea and the vestibule. Depending on the time lapse between the acute event and imaging, as well as on the concentration of the different blood products (methemoglobin), the signal intensity on T1/T2 weighted sequences may vary. Recent articles show that 3D FLAIR imaging is more sensitive than other MRI sequences for the detection of intra-labyrinthine hemorrhage. Conclusion: Although rare, SNHL may be caused by pathologies that are visible on MRI imaging. MRI FLAIR Imaging allows not only for the detection of the hemorrhage itself but also permits a differentiation from other causes of hypersignal in MRI such as lipomas, which can also cause SSNHL.
