That can be from anything that increases the pressure in the brain such as swelling, bleeding or masses and is called herniation.
It can be from a birth defect known as a Chiari malformation.

∙ 13y agoThe wedging of medulla oblongata into the foramen magnung is termed "incarceration".
This the result of pressure build-up in the brain.
This pressure build-up is typically caused by swelling of the brain, bleeding in the brain (as caused by a vessel-rupture, ie.: anurism) og by blocked drainage of the cerebrospinal fluid - often known as fluid in the brain or "hydrocephalus).

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.
