A 2 year study of meningiomas in correlation with squash cytology and histopathological examination

ABSTRACT

Background: Meningiomas are common CNS tumors arising from the meningothelial cells and usual sites are intracranial, followed by intra spinal. WHO 2007 has categorised meningiomas into 3 grades. This grading helps in predicting their behaviour and treatment. Aim and objectives: To study the frequency, clinical details, histological typing of meningiomas in comparison with squash cytology (intra operative diagnosis) and Histopathological examination post operatively. Materials and methods: The present study was a prospective study conducted from May 2015 to April 2017 in the Department of Pathology, Gandhi Hospital. We received 50 clinically as well as radiologically diagnosed cases of meningiomas, which were compared with squash cytology and Histopathological examination. Results: In our study, meningiomas constituted 15% of all CNS tumors received from the Neurosurgery Department in a period of 2 years. In the present study, the number of Meningiomas was 50. Females outnumbered males (36 out of 50). Common site was intracranial (45), followed by intra spinal-thoracic (5). The commonest sub type was meningothelial variant of meningioma (12), followed by transitional variant (11). Squash cytology matched with the Histopathological examination in 91.15% cases. Conclusion: Meningiomas are predominantly occur intra cranially with female preponderance, majority were of benign grade I neoplasms. Squash cytology plays a major role in their intra operative diagnosis.
