Tumors of the central nervous system (CNS) are estimated to be approximately 2% of all new cancers. In India, they constitute about 1.9% of all tumors. Extramedullary lesions, most commonly benign meningioma, account for 70 to 80% of spinal cord tumors. The objective of this study is to characterize histological subtypes, age and gender distribution, and WHO grading of intracranial and spinal tumors in a tertiary care hospital in Jaipur, Rajasthan, India.  \nMaterial and method  \nA retrospective study was conducted at the Department of Surgical Oncology, Sawai Man Singh (SMS) hospital, Jaipur, Rajasthan, a tertiary care hospital, over a period of 5 years. A total of 1315 cases of CNS and spinal neoplasms were diagnosed during this period.  \nResults  \nIn this study, a total of 1315 cases of CNS and spinal tumors were found. The majority (1199 cases, 91.2%) of the tumors were intracranial, whereas the remaining 116 (8 .82%) cases were spinal. Among intracranial tumors, astrocytomas accounted for the largest share in our study, comprising 398 cases (30 .27%), mostly seen after the 3rd decade of life, with a mean age of occurrence of 28 .44 years. Glioblastoma multiforme forms the largest subtype, constituting 41.96% of all astrocytoma, mostly seen in the 5th or 6th decade of life. Meningioma constitutes the second major group of tumors involving the CNS. Overall, males outnumbered females, the ratio being 1.66: 1. However, meningioma is an exception, which was found with higher rates in females (ratio 1 : 1.37) . Among the spinal neoplasms, meningioma was the most common type in our study.  \nConclusion  \nThe most common type of intracranial tumor in the present study was astrocytoma, followed by meningioma. The ratio of male: female for CNS tumors was 1.66: 1. However, females outnumbered males in the case of meningioma, with a ratio of 1: 1.37. Meningioma was the most common type of spinal neoplasm.  \nCategories: Oncology  \nKeywords: astrocytoma, cns, intracranial tumor, meningioma, spinal tumor  \nIntroduction  \nBrain and surrounding tissue tumors, known as intracranial neoplasms, form a diverse group within central nervous system (CNS) cancers, encompassing both non-cancerous and cancerous types [1] . These CNS growths make up roughly 2% of newly diagnosed cancers worldwide, a figure consistent across European and non-European groups [2-4]. In India, they account for about 1.9% of all tumors, though rates climb higher in wealthier nations. Brain tumor cases show a bimodal age pattern, peaking in childhood and again between ages 45 and 70 [5-6].  \nAdult CNS tumors often differ from pediatric ones in location and type. Children’s tumors frequently develop in the posterior fossa, while adults see most in the anterior regions.
