Abstract
Background: Atypical meningiomas form a small group among meningiomas and are characterised by distinct natural history and outcome. Pre-operative detection of atypical meningiomas can help in streamlining the management.
Methods: This study was done at Government Medical College, Trivandrum over a 3 year period. Study population included the patients with meningiomas sent for Magnetic Resonance Imaging, who were investigated by previous CT scan. Sample size was 183. Study design was Observation study. Final pathological diagnosis in all patients was confirmed by biopsy and histo-pathological examination.
Results: Of the 183 cases studied, 165 cases were typical meningiomas, 15 were found to be atypical and 3were anaplastic.
Conclusion: MR imaging is sensitive in differentiating between typical and atypical meningiomas and can be used as a problem solving study when there is diagnostic dilemma with CT scan showing indeterminate findings. This makes conventional advanced MRI as the imaging of choice in meningiomas.
Key Words: Meningioma; Atypical; MRI Brain tumours.
