Abstract: Only 1.8-3.2% of all meningiomas are located at foramen magnum (FM). As these tumours are indolent, there occurs a long interval between onset of symptoms and diagnosis. This diagnostic delay may get accentuated, if unusual clinical features or radiological features are seen. The authors present two cases of FM meningiomas, with rare radiological features, one with intense bony hyperostosis and another with circumferentially, constricting en-plaque meningioma.
