The judgment of benign and malignant of vertebral canal tumor can be judged from the growth characteristics, auxiliary examination, puncture pathology and other aspects.
1. Growth characteristics: benign tumors in the spinal canal usually grow slowly, have a clearer demarcation with the surrounding tissues, seldom encroach on the surrounding tissues, and do not metastasize; whereas malignant tumors in the spinal canal grow faster, have a blurring of the demarcation with the surrounding tissues, and may have encroachment on the bone and nerve tissues, and metastasis may also appear in the late stage.
2. Auxiliary examination: benign and malignant tumors in the spinal canal can also be judged by intensive CT or nuclear magnetic resonance, benign tumors usually have a limited lesion scope, with little destruction of the surrounding bone, and the nerve tissues may be compressed or have the signals of spinal cord edema; malignant tumors usually have a more diffuse lesion scope, with the destruction of the bone, and the tumor is often poorly demarcated from the signal of the nerve tissues.
3. Puncture pathology: Pathological puncture is the gold standard for determining the benign or malignant nature of tumors in the spinal canal. The puncture results of benign tumors in the spinal canal usually belong to normal tissues of the body, and connective tissue hyperplasia is possible; while malignant tumors in the spinal canal usually can see cancer cells or heterogeneous cells, which may be accompanied by a large number of fibrous tissue hyperplasia.
In order to detect vertebral canal tumors in time, it is recommended to have a good physical examination on a regular basis and to have regular treatment as soon as possible after detection.
