Hydromyelia can be described as CSF build-up within the spinal cord leading to a syrinx near the which area?

Hydromyelia can be described as CSF build-up within the spinal cord leading to a syrinx near the which area?

• A. Near the fourth ventricle
• B. Near the third ventricle
• C. Near the lateral ventricles
• D. Within the brain parenchyma

Answer: (A)

Hydromyelia is the dilation of the spinal cord’s central canal due to CSF buildup. The central canal is continuous with the fourth ventricle at the rostral end of the spinal cord, so when CSF accumulates, the expansion occurs near that junction, creating a syrinx close to the fourth ventricle. The other ventricles (third or lateral) are part of the brain’s ventricular system and are not directly involved with the spinal central canal, nor is the issue described as located within brain parenchyma.
