Objectives The present study aims to categorize the prevalence of intracranial tumors surgically treated at the neurosurgery service of Hospital Universitário Evangélico Mackenzie (HUEM) between 2016 and 2018. Material and Methods This survey included patients surgically treated due to primary or metastatic intracranial neoplasia between 2016 and 2018 at a referral center in the city of Curitiba. These patients were analyzed for epidemiological, histopathological, and topographic data, and they underwent an assessment of the outcome at the time of hospital discharge. Results A total of 96 patients met the inclusion criteria. The most prevalent tumor was the glioma, with 39.6% of the sample, with glioblastoma being the most prevalent histological type. Brain metastases and meningiomas represented, respectively, 21.9% and 18.8% of the total. There was a predominance of supratentorial and intra-axial tumors in our sample. Conclusion Glioma was the most commonly found tumor, directly associated with high morbidity and mortality. The development of new and more effective drugs with action directed at the molecular level of intracranial tumors may be the path to a longer survival and improvement in the quality of life of these patients.
