syringobulbia

When syrinxes affect the brainstem, the condition is called syringobulbia.)

None Syringobulbia is a neurological disorder characterized by a fluid-filled cavity (syrinx) within the spinal cord that extends to involve the brainstem (medulla).

If the syrinx is higher up in the spinal cord or affecting the brainstem as in syringobulbia, vocal cord paralysis, ipsilateral tongue wasting, trigeminal nerve sensory loss, and other signs may occur.

In medicine, a syrinx is a rare, fluid-filled neuroglial cavity within the spinal cord (syringomyelia), in the brain stem (syringobulbia), or in the nerves of the elbow, usually in a young age.
