Cervical Syrinx with Chiari I


MR – Sagittal T1 and T2 images show “pegged” cerebellar tonsils extending to the level of C2 with fusiform syrinx at the cervicothoracic junction.


Chiari I malformation is defined by downward displacement of the cerebellar tonsils of 5 mm or more. Although Chiari I malformation is not usually associated with other intracranial abnormalities, syringomyelia is found in 20–70% of patients, depending on the degree and extent of disruption of normal cerebrospinal fluid flow between the spine and cranium. Syrinx associated with Chiari I malformation is more common in older children, girls and those with greater degree of CSF obstruction. Surgical decompression at the craniocervical junction often resovles the syrinx and associated neuronal dysfunction although occasionally syrinx shunting is required.
