Abstract

Background: Cerebellar tumors are considered as clinically significant intracranial neoplasms and
acknowledgment of their epidemiological characteristics tends to be essential. The present study was
conducted in order to determine the prevalence and types of their cerebellar tumors in Shohada-e-Tajrish
Hospital between 2006-2014.
Materials and Methods: In the current observational descriptive study, 105 patients with brain cerebellar
tumor in Shohada-e-Tajrish Hospital from 2006 to 2014 were included in the study and prevalence and types
of their cerebellar tumors were determined.
Findings: According to the results, hemangioblastoma (15.2%), schwannoma (12.4%), pilocytic astrocytoma
(13.3%), medulloblastoma (18.1%), and meningioma (9.5%) were the most common cerebellar tumor types.
Age correlated with tumor’s type (P=0.0001). Meningioma was more common among older patients, while
choroid plexus tumors were more seen among younger patients. The gender and clinical symptoms did not
have any correlation with tumor type (P > 0.05).
Conclusion: It can be concluded that prevalence and types of cerebellar tumors in our center are similar to
the worldwide incidence trend
