Aim: Epidermoid cyst is an uncommon ectoderm originated benign cyst. Although intracranial epidermoid cyst may commonly occur in the cerebellopontine angle and chiasma opticum, it can be detected in cerebral hemispheres as well as intraventricular area. Syringomyelia, a progressive hydrodynamic disorder of spinal canal usually occurs in cervical region although it can be seen in thoracic and lomber portion of the spinal cord. Case report: We describe a patient with syringomyelia associated with posterior fossa located epidermoid cyst. Siringomyelia has been spontaneously regressed after the removal of the posterior fossa epidermoid cyst. Conclusion: Primary intervention to spinal cord cavitations must be avoided because it can be spontaneously regressed after the removal of the posterior fossa tumor.

Epidermoid cyst refers to the implantation of epidermal elements into the dermal and deeper tissues. In head and neck, incidence ranges from 1.6 to 7%. In the tonsillar area it is extremely rare i.e less than 0.01%. They occur in fetal period  as congenital lesion or as an acquired lesion  either due to a trauma or  as post surgery implant. In this case report, we will discuss the epidermoid cyst, in a 46-year-old male who presented with history of pain in the throat with previous history of bilateral tonsillectomy.
