Review of Epemdymoma in the Shohada-y- Tajrish Hospital

Ependymoma constitute 5 % to 7 % of all primary CNS neoplasm. But their prevalence relative to other tumor type varies with patient age and presenting location. Ependymoma constitute approximately 1O % of intracranial neoplasm in pediatric population and up to 30 % of those encountered in children under 3 years of age. In spinal column, ependymoma constitute 60% of glial neoplasm, and opposed to intracranial tumors. These neoplasm exhibit a decided preditection for the fourth and five decade of life In these research which has done upon 25 patients with ependymoma in the Shohadaye Tajrish Hospital during the years 1372 to 1376, Thirteen of patients are male and 12 of them are female. The tumor has been more common between the ages of 0-20 years old in intracranial neoplasm and 21-30 years old in­intraspinal neoplasm. Headache and lumbar pain have been the most common clinical manifestation. The majority (22) of lesions in conventional histologic grading have been low grade (Grade I,II) and the rest (3) high grade (grade III.IV).
