Introduction: Meningiomas are a histologically diverse group of tumors derived from meningothelial cells. In this present study the clinical features, anatomical location, and histopathological spectrum of Meningioma were studied.
Materials and Methods: The study included 103 CNS tumors operated during a one-year period in various hospitals and clinics of dhaka, Bangladesh. All the cases of meningioma were studied by histopathological examination using H&E staining.
Results: In this study, the most common age group was 40-49 years (35%). Female predominance (73.8%) was noted. Intracranial meningiomas (90.90%) were common than spinal meningiomas. The most common histopathological type was meningotheliomatous meningioma (50%). 94.3% of the meningioma was WHO grade I tumor.
Conclusion: Meningiomas display a wide diversity of histopathological appearances. The majority are benign and hence curable by surgical resection. A few histological features and variants are associated with aggressive behavior and high risk of recurrence. Thus accurate histopathological diagnosis and grading of these tumors are essential.
