Tinnitus affects approximately 10% of the general population, but in more than half of the patients no cause is found even after extensive evaluation. The most frequent causes of progressive unilateral nonpulsatile tinnitus are acoustic neuroma, skull base tumor, labyrinthitis, and vascular compression syndrome. The vascular malformations usually noted are expanding processes of the internal auditory meatus (eg, hemangiomas) and vascular loops formed by arteries, usually the posteroinferior cerebellar artery. We report an exceptional case of tinnitus associated with a cerebellar venous angioma with the draining vein crossing the acousticofacial bundle at its origin.
REPORT OF A CASE
A 55-year-old man had a 2-year history of permanent, subjective, nonpulsatile, isolated tinnitus in the right ear. At admission, general physical examination and otoscopy yielded normal findings. Audiograms showed bilateral sensorineural hearing loss (Figure 1). The intervals . . . [Full Text of this Article]
