ABSTRACT

Study Design: A case report. Objectives: To report a rare case of epidermoid cyst in the spinal canal. Summary of Literature Review: Epidermoid cyst in the spinal canal is rare. Idiopathic epidermoid cyst in the spinal canal notassociated with a trauma or infection is even rarer. Material and Methods: A 73 year-old female presented with a 1 year history of progressive paresthesia and motor weakness of bothlower extremeties. MRI showed a cystic mass on the 7th thoracic canal. We performed total laminectomy at the T6 –T8 level. The cysticmass was excised after durotomy using a posterior approach. Results: We confirmed the presence of an epidermoid cyst for histopathology. Conclusion: Idiopathic epidermoid cyst in the spine is very rare and requires accurate differential diagnosis. Preoperative MRI scans arenecessary to differentiatie epidermoid cysts from other intradural masses. Confirmative diagnosis can be done by histopatholoty.
