Spinal cord tumors are classified into benign and malignant tumors, commonly including astrocytoma, ventricular meningioma, nerve sheath tumor, etc. The benign and malignant nature of spinal cord tumors can be identified through imaging examination and pathological examination. 1. Imaging examination: To determine the benign or malignant nature of spinal cord tumors, imaging examination such as MRI can be used to assist the judgment. Benign spinal cord tumors usually have regular shape, uniform density and smooth edges, while malignant tumors usually have irregular shape, burr sign, lobulation sign, uneven density, unclear edges, adhesion with surrounding tissues and peri-tumor edema. 2. Pathological examination: imaging examination can make preliminary judgment on the benignness or malignancy of spinal cord tumor, while pathological examination can make clear diagnosis on the benignness or malignancy of spinal cord tumor as well as its specific type. Usually, postoperative histologic examination can be performed after surgical resection. It should be noted that if symptoms such as numbness in the spinal cord area, radiating pain, urinary incontinence, etc. occur, go to the hospital in time to improve the examination and receive treatment.
