UNASSIGNED: Central nervous system (CNS) @entity5 are the most frequent @entity5 in @entity1 and adolescents. The epidemiology of these @entity5 differs in areas of the world. However, very little data is available in the low/middle income countries (LMIC). The aim of this study is to describe the characteristics of @entity1313 treated at a leading LMIC pediatric @entity5 hospital and its difference from that in other countries. One thousand one hundred fourteen @entity1 and adolescent having CNS @entity5 were treated in the largest pediatric @entity5 hospital in the Middle East during a period of 5    years. They were diagnosed histopathologically in 80.2  %, through medical imaging in 19.4  % and via both @entity5 markers and imaging in the remaining 0.4  % of cases. Through epidemiological analysis was performed using all available @entity1 ' data revealed that 96  % of the @entity1 had primary @entity1313 , while only 4  % the @entity75 was in the spinal cord. The most common histological type was @entity5 (30.0  %, pilocytic (GI)  =  13.2  %, GII  =  10.5  % and GIII  +  IV (high grade)  =  6.3  %) followed by @entity5 (23.2  %, @entity2946  =  18.7  %, PNET  =  2.8  %, ATRT  =  1.5  % and @entity6196  =  0.2  %) then @entity424 in 8.7  %, craniopharyngeoma in 5.3  %. The mean age at diagnosis was 7.1      4.2  years which did not differ significantly by gender nor residency but it differed by the pathological subtype. The frequency of each pathological type was different among different age groups. Though the present study was a hospital-based analysis in a low/middle income country, yet it did not differ from the well-established population-based study reports in the high income countries.
