**1. Overview**

Tumors of the central nervous system are the most common solid tumors in the pediatric age group and the second most common childhood malignancy. They are the leading cause of morbidity and mortality associated with cancer. Although it affects all ages, the incidence peaks among children between the ages of 3 and 7. In adults and older children, most tumours are supratentorial in location while in young children they are more commonly infratentorial in location [1].
