Central Canal or Syrinx-MRI Teaching Point
This is a question which some of us have to answer occasionally when we see prominent central canal, which looks a bit more prominent than usual.
Following points will help you to decide in favor of the normal variant are-
- The central canal of the spinal cord is present at birth and becomes progressively obliterated. But it may persist partially or completely.
- Central canal is located at the junction of the ventral 1/3 and dorsal 2/3 of the spinal cord and is filiform in shape and located in the thoracic cord most commonly. There should not be factors (Chiari malformation, dysraphism) predisposing to syringomyelia.
Once you see these points these suggest persistent central canal, which is just a variant of normal anatomy.
