Syringomyelia MRI

Normally, the spinal cord and brain are bathed in a fluid called cerebrospinal fluid. Syringomyelia is an accumulation of spinal fluid that actually forms within the spinal cord. This accumulation is called a syrinx. Most of the time, syringomyelia is caused by Chiari malformations, which is a birth defect of the back and lower part of the brain.
