Spinal epidermoid tumors are rare tumors, constituting about 1.5-2% of the spinal tumors. Cervical and thoracic spinal cord epidermoid tumors are exceedingly rare. We reported a case of a 28-year-old patient with an intradural extramedullary epidermoid cyst at the thoracic region presented with urinary incontinence and paraparesis to our outpatient clinic. First symptoms of patient started 16 years ago and diagnosed as peroneal muscular atrophy and he couldn’t be investigated sufficiently. Because of the delayed diagnosis and treatment, paraparesis and urinary incontinence were persistent in spite of successful surgery and proper physical therapy. Spinal epidermoid tumors have a good prognosis, as they are histologically benign. When diagnosed early, complete surgical resection offers the patient good neurologic outcome. It is important to investigate extensively patients with neurological deficits and to make diagnosis as soon as possible.
