Not really: Unless the cerebral tonsils are below the foramen magnum and you have clinical signs of hydrocephalus or enlargement of the ventricles in your brain, you don't have any worries.

What does it mean when my MRI results say that my cerebellar tonsils are seen low lying 4.2mm below, suggesting chiari malformation?

Chiari malformation: What you're describing is a typical finding for a chiari type 1 malformation. Chiari malformation is basically when part of the brain (cerebellum) sits below the base of the skull. This may cause headaches, weakness, trouble swallowing/speaking, numbness of the arms....Many different symptoms are possible. It also can be asymptomatic. Get a neurological or neurosurgical evaluation.
