Experts call these low-lying cerebellar tonsils Chiari malformation type 1 (CM-1). Although Chiari I malformations are often isolated abnormalities, the following findings may be seen in association: cervical cord syrinxin ~35% (range 20-56%): more common in symptomatic patients, the relationship remains poorly understood and whether the hydrocephalus or Chiari 1 malformation is the primary abnormality continues to be debated 12, abnormal CSF flow dynamics through the central canalof the cord and around the medulla, posterior fossa size, intracranial pressure and venous pressures have all been implicated as potentially contributory 13. skeletal anomalies in ~35% (range 23-45%)2,3: Unlike Chiari II, III, and IV malformations, Chiari I malformations often remain asymptomatic until adulthood if it ever becomes symptomatic. In many individuals, the posterior fossa is abnormally small, which may lead to the growing brain being pushed down through the normal opening (foramen magnum) where the brain and spinal cord meet.
