Dilatation of the central canal of the cervical spinal cord is mainly due to spinal cord cavernous disease (spinal cord cavernous with blockage of the median foramen of the fourth ventricle and enlargement of the central canal), which is usually reviewed after 1 month after surgery.
Delayed spinal cord CT scanning (DMCT, i.e., injecting contrast agent into the subarachnoid space) for spinal cord cavernous disease was performed 6h, 12h, 18h, and 24h after injection of the contrast agent, which could clearly show high-density images of the cavern. Magnetic resonance imaging (MRI) sagittal images can show the location, size, and extent of dilation of the central canal of the cervical spinal cord.
Spinal cord cavernous disease progresses slowly, and there is no specific treatment measure at present. Symptoms can be relieved by medication and surgery. The surgical methods include upper cervical segment laminectomy and decompression, suboccipital decompression, cerebrospinal fluid shunt, etc. Regular review should be conducted at 1 month, 3 months, 6 months and 1 year after the surgery in order to understand the recovery of the disease.
If the above symptoms occur, it is recommended to go to the hospital in time for early and regular treatment.
