Auditory neuroma may cause hand numbness. Auditory neuroma is a benign intracranial tumor, which occurs in the area of the bridge cerebellar angle, a region densely populated with blood vessels, nerves, and important brain tissues, including the brainstem, the most important structure in the cranium. The tumor may compress the brainstem, causing damage to the nerve fibers within the brainstem, causing motor and sensory disorders of the limbs, and symptoms such as paralysis, numbness, and loss of sensation of the limbs. In case of surgical treatment of acoustic neuroma, the tumor may be tightly connected to the brainstem, and the process of separating and removing the tumor during the surgery may cause harassment and damage to the brainstem, which may also lead to numbness of the hands and legs after the surgery.
