Abstract:

Purpose: Epidermoid cysts are rare ectodermal-based salmon cysts. The epidermoid tumors that are seen inside the head often hold the corner of serebellopontin, the chest area, but can also be seen in the hemispheres of the brain and intraventricular spaces. Siringomyeli is a progressive hydrodynamic disorder of the spinal canal, and although it is often seen in the cervical area, it can also be seen in the torasic and lomber levels. The case presentation: a nine-year-old male patient who was diagnosed with the association of the Posterior fossa epidermoid cyst with siringomyeli, after the intervention of the posterior fossa epidermoid tumor, the siringomyeli had a recession of itself. The result: As it is possible to remove siringomyeli by intervention in the Posterior fossa tumor, it should be avoided to interfere in the cavitation of the spinal cord first.
