Abnormal vertebral signal is usually described by MRI. It may be a local hemangioma, a local inflammation, or even a local tumor and other conditions. Abnormal signal of vertebral body only suggests that there is a difference with the normal tissue signal, which needs to be combined with the comprehensive judgment of MRI images. If there is local inflammation, the signal is generally high; if there is a local tumor, in addition to signal abnormalities, usually accompanied by bone destruction, etc., can be further combined with local CT, and three-dimensional reconstruction to determine the cause of the abnormal signal of the vertebral body. If it is caused by inflammation, anti-inflammatory drugs, such as cephalosporin, can be selected for treatment. If it is a tumor, etc., surgery can be considered.
