Treated syringomyelia by occipital craniectomy

Case contributed by Dr Chris O'Donnell


Numb hands, ? cervical radiculopathy

Patient Data

Age: 55 years
Gender: Female

Before and after posterior fossa decompression

Subtle tonsillar herniation through foramen magnum with cystic space in the mid-cervical cord (in the line of the central canal). 

Following posterior fossa decompression with normal-appearing cerebellar tonsils and near resolution of the "syrinx" (and the patient's symptoms). 

Case Discussion

Resolution of syringomyelia following posterior fossa decompression alone indicates that the alteration to CSF flow dynamics caused by tonsillar herniation leads to syringomyelia (even focal central canal expansion) and that it can be corrected by re-establishment of normal CSF outflow from the IVth ventricle
