This is not a good sign really.
It means the pressure inside the skull has increased, usually post trauma or infection causing the brainstem to move downwards into the hole in the skull from which the spinal cord arises from. Imagine squashing a bowl of rather solid jelly into a large bore hosepipe...it doesn't fit very well.

My 4 year old was diagnosed with having cerebellar tonsils extending below the foramen magnum what does this mean?
Cerebellar tonsils are parts of the cerebellum of which there are two that lie one on either side of the vermis. The foramen magnum is the large hole in the base of the skull through which a few things pass most importantly the spinal chord. If the cerebellar tontils are also trying to get down through the foreamen magnum then they will put physical pressure on the spinal chord. The result is dependant on the pressure being exerted but likely includes motor and sensory abnormalities.

What is this slight encroachment by the cerebellar tonsils on the foramen magnum without high grade Chiari malformation?
The cerebellar tonsils are crowding or pushing down toward the foramen magnum which could be nothing to worry about unless you have a lot of headaches, neck pain, numbness in arms, tingling in hands...could be the cause for that and really, the only thing you can do to stop that IF that's the cause is surgery which isn't 100A% effective.
