Background: Brain tumors are associated with marked disability and mortality. Understanding the patterns and epidemiological characteristics associated with brain tumors can be crucial to their treatment.

Objective: To explore the magnitude and epidemiological features of primary brain tumors among patients admitted to Aseer Central Hospital (ACH), Abha City, Saudi Arabia, and to identify different decisions for their management. Methodology: All hospital records of brain tumor patients admitted to ACH from 2015-2017 were reviewed. Collected data included patients' demographic characteristics, clinical findings, histopathological diagnosis, and management.

Results: During the aforementioned period, a total of 100 patients with primary brain tumors were admitted to ACH. The most commonly presenting symptoms were headache (72%), vomiting, dizziness, and focal motor deficits (25% for all). Tumor location was mostly at the frontal or parietal lobes. Among those who underwent surgery, meningioma grade I was the most frequently diagnosed (41.7%). The mean surgical time was 4.2 ± 1.6 h. Most patients who underwent surgery at ACH stayed in the intensive care unit anywhere from 1 d or 2-4 d (34% and 40%, respectively). The Glasgow outcome scale scores of most patients (91.7%) indicated that the patients had a good recovery. However, one patient died (1.7%), one was in a persistent vegetative state (1.7%), and three sustained moderate disability (5%).

Conclusion: Most patients with brain tumors admitted to ACH undergo surgery. Meningioma grade I is the most commonly encountered brain tumor, and this finding may reflect different epidemiological findings from the internationally accepted concept that glioblastoma multiforme is the most common brain tumor. The most common locations for brain tumors are the frontal and parietal lobes.
