Plain-English summary
A 5-year-old toy poodle was brought in because it was having trouble walking and was weak in all four legs. The vet discovered that the dog had a condition called syringomyelia, which was linked to a brain malformation. Using a special imaging technique, the vet could see how the cerebrospinal fluid (CSF) was flowing in the dog's brain. After surgery to improve the CSF flow, the dog showed significant improvement and was able to walk better again.

Abstract
A 5-year-old toy poodle was referred for progressive non-ambulatory tetraparesis caused by cervicothoracic syringomyelia associated with Chiari-like malformation. At presentation, the cerebrospinal fluid (CSF) flow pattern was atypical on time-spatial labeling inversion pulse images with evidence of greater volume flow through the mesencephalic aqueduct and atypical to-and-fro flow in the fourth ventricle and into the syrinx. In this dog, the definition of CSF flow pattern using this imaging technique before surgery aided in classifying pathogenesis and suggested the utility of ventriculoperitoneal shunting, which normalized CSF flow and resulted in a good clinical outcome.
