What may cause medulla oblongata to be wedged into foramen magnum?
This is called a tonsillar hernation, where the cerebellum is pushed through the foramen magnum. The extra brain trying to pass through the foramen magnum can cause compression of the medulla, which has serious complications (e.g. stop breathing.) This may be due to a space occupying lesion somewhere else in the brain, or in the cerebellum itself. As the brain cannot expand outwards (due to the hard skull) it expands down (and across where possible). Examples of space occupying lesions include haemorrhage, oedema and tumours.
