Yes though it is extremely rare it has been proven that it can cause a rare form of sudden death syndrome by forming a lethal brain stem compression.
Chiari malformation can become a progressive disorder and lead to serious complications:
Hydrocephalus: accumulation of excess fluid within the brain
Syringomyelia: a cavity or cyst (syrinx) forms within the spinal column
Paralysis, which may occur due to the crowding and pressure on the spinal cord, tends to be permanent, even after treatment with surgery
Sudden Death: Lethal brain stem compression may accompany even relatively minor trauma associated with chronic cerebellar tonsillar herniation in patients with Chiari I malformation.

No but left unattended, it has the potential to become life-threatening in the future!
An Arnold-Chiari malformation is an alternative name for a Chiari malformation, a malformation of the brain consisting of a downward displacement of the cerebellar tonsils through the foramen magnum.
No but left unattended, it has the potential to become life-threatening in the future!
