[|AI|]  Hi, Thank you for posting your query. This condition is called Chiara malformation. In this condition, the cerebellar tonsil Chat Doctor. If the compression on the brain stem or cervical cord is significant, then, a surgery is required, called as foramen magnum decompression. Chiari malformation is normally present since birth. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health,
