Summary
This study analyzed 210 intracranial neoplasms, finding gliomas to be the most common type in both adults and children. Metastatic tumors were the second most frequent, with no significant gender predilection observed in tumor distribution.
Area of Science:
- Neuropathology
- Oncology
- Epidemiology
Background:
- Intracranial neoplasms represent a significant health concern with diverse histopathological variants.
- Understanding the distribution patterns and demographic variations is crucial for diagnosis and treatment.
Purpose of the Study:
- To investigate the histopathological patterns of intracranial neoplasms.
- To determine the relative distribution of these variants across different age groups.
- To identify any existing gender differences in the occurrence of these tumors.
Main Methods:
- A case control study was conducted.
- Analysis of 210 histologically confirmed intracranial neoplasms over an eleven-year period (1980-1990).
- Tumor slides were stained using standard histological techniques (Hematoxylin and Eosin, Reticulin, Phosphotungstic acid Hematoxylin).
Main Results:
- Gliomas constituted the largest proportion of intracranial neoplasms, followed by metastatic tumors.
- Astrocytoma was the most prevalent glioma subtype.
- Craniopharyngiomas were more common in children, and no significant gender difference was observed (1:1 ratio).
Conclusions:
- Gliomas are the most frequent intracranial neoplasms in both pediatric and adult populations.
- Metastatic tumors are the second leading cause of intracranial neoplasms.
- Tumors of the sella turcica predominantly affect children, and brain involvement in Burkitt's lymphoma is more common in African populations.
