Histopathological analysis of meningioma and its variants: A study of fifty cases
1Department of Pathology, Pratima Institute of Medical Sciences, Karimnagar, Telangana, India.
Background:
The study was conducted to know the various histopathological variants of meningiomas, the age incidence and sex ratio.
Materials And Methods:
A retrospective and prospective analysis of all the samples sent for histopathology for 2 years during June 2013-May 2015 was done to diagnose meningioma and its variants. Cases were analyzed in detail about the complete clinical history, exact location, and clinical and radiological diagnosis. The majority of the cases were clinically and radiologically diagnosed as meningioma.
Results:
Of 50 cases which were diagnosed as meningiomas, 21 were meningothelial variant, 15 were psammomatous, 8 were fibroblastic, 4 were transitional, and 1 case each of anaplastic and atypical variant. The most common age group was between 41 and 50 years. The youngest age group was 16 years and oldest was 70. The male:female ratio was 1:1.5.
Conclusion:
The majority of the meningiomas have been observed between 41 and 50 years. Their proper recognition is therefore important to allow appropriate treatment. Histopathological study plays a major role by which we can diagnose the lesion. Meningiomas typically develop in middle-aged individuals and occur more frequently in women than men. These lesions may also occur in children.
