Background. Brain tumor is a rare tumor with low incidence. Although it is a rare tumor, the mortality of brain tumor is disproportionately high. Many countries have already published epidemiology of brain tumor. However, the epidemiology of brain tumor in Indonesia remains to be investigated. This article aimed to provide descriptive epidemiology of brain tumor. Methods. The data of brain tumor acquired from Department of Neurology and Neurosurgery Cipto Mangunkusumo General Hospital from 2014 to 2016. The histopathology classification of primary intracranial tumors was based on WHO classification of CNS tumors 2016 while brain metastasis was classified based on other histopathological types. The variables were analyzed and presented descriptively. Results. There were 316 subjects acquired in this study. Most of the subjects (68%) were women. The mean age of this study was 43.8 (11.7). Most of the subjects (86.1%) had primary histopathology. Lung cancer was the most commonly found brain metastasis in this study (34.1%). Conclusions. This is a pilot study of brain tumor epidemiology in Indonesia. Collaboration with other centers in Indonesia is needed to give a more representative insight of brain tumor in Indonesia.
