The possible causes of cervical spinal cord signal abnormality in the horizontal segment of the cervical 6/7 vertebrae found during MRI include tumor, intravertebral hematoma, abnormal fat deposition, and osteochondritis dissecans of the vertebral endplates. 1. Benign tumors such as hemangioma, malignant tumors such as hemangioblastoma, astrocytoma, and ventricular meningioma can be detected as abnormal signals in the cervical spinal cord during magnetic resonance examination. 2. Intravertebral hematoma: Bleeding caused by trauma may also show abnormal signal in the cervical spinal cord. 3. Abnormal fat deposition: It may be caused by long-term use of hormones or obesity, etc., and may also show abnormal signals in the cervical spinal cord. 4. Vertebral endplate osteochondritis dissecans: This is an aseptic inflammation of the endplate cartilage, and because of the inflammatory stimulus, cervical spinal cord signal abnormalities can also occur. The causes of cervical spinal cord signal abnormality in the horizontal segment of the cervical 6/7 vertebrae are many, and may also be related to the trabecular changes of the vertebrae after the fracture, etc. It is recommended that further diagnosis and treatment be made under the guidance of a doctor.
