Ectopic cerebellar tonsils have been reported previously in cases of M-CMTC, and this phenomenon may be a secondary event associated with brain overgrowth rather than due to a ...
Note that the ectopic cerebellar tonsils are positioned snugly in the posterolateral subarachnoid space of the cervical spinal canal. Sagittal T1-weighted magnetic ...
When ectopic, the cerebellar tonsils may be elongated and take on a pointed appearance inferiorly discribed as "peg-like". When there is extension of the tonsils greater than ...

The anomalous vertebral arteries severely compressed the posterior aspect of the cord with a resultant intramedullary T2 signal change. Ectopic cerebellar tonsils caused further ...
Radiographically, the cerebellar tonsils are ectopic, or descend through the foramen magnum at least 5mm into the cervical spinal canal. The 5mm cutoff is somewhat arbitrary, as ...
