Which tract is affected in syringomyelia?
The basic pathology in syringomyelia is a progressively expanding cavity in the central spinal canal. This expanding CSF filled “syrinx” compresses the spinothalamic tract neurons decussating in the anterior white commissure. However, the posterior columns are spared as they are located distally.
What is syringomyelia and syringobulbia?
Syringomyelia (central cavitation of the spinal cord) and syringobulbia (cavitation of the medulla) are relatively rare disorders. These conditions are often found in association with congenital abnormalities such as Chiari malformations, with neoplasms or as sequelae to spinal cord trauma.
Can syringomyelia be cured?
Surgical removal of obstructions such as scar tissue, bone from the spinal canal, or tumors can help restore the normal flow of CSF. If a tumor is causing syringomyelia, Removing a tumor that is causing syringomyelia almost always eliminates the syrinx. Occasionally, radiation also may be used to shrink the tumor.
What is the life expectancy of someone with syringomyelia?
Lately, the number of patients that remain stable grow, although an older study suggested that 20% of patients suffering from Syringomyelia died at an average age of 47[4].
How is syringobulbia diagnosed?
The diagnosis of syringobulbia is made by means of neuroimaging, typically magnetic resonance imaging (MRI).
What causes syringobulbia?
Syringobulbia is a disorder of the lower brainstem caused by progressive enlargement of a fluid-filled cavity that involves the medulla and almost invariably the spinal cord (syringomyelia). The symptoms and signs are caused by dysfunction of the central spinal cord.
Does syringomyelia affect breathing?
In some cases of syringomyelia, the cyst grows into the brain stem and interferes with vital functions such as breathing and heartbeat. This complication is called syringobulbia. Some of the symptoms of syringobulbia may include: swallowing difficulties.
