Abnormal signals in the cervical 5 vertebrae are usually described by MRI, not necessarily tumors, but also abnormal fat deposits, intravertebral hematomas, vertebral endplate osteochondritis dissecans, and so on. 1. Tumor: it can be benign tumor or malignant tumor. Benign tumors, such as hemangiomas, and malignant tumors, such as ventricular meningiomas, hemangioblastomas, and astrocytomas, can be detected by magnetic resonance imaging with abnormal signals in the vertebral body. 2. Abnormal fat deposition: It may be caused by obesity, long-term use of hormones, etc., which may also show abnormal signals in the vertebral body. 3. Intravertebral hematoma: Most of the patients have suffered from traumatic injury, such as falling down while walking, car accidents, etc., which leads to intravertebral hemorrhage, and abnormal signals of the vertebral body can also be found during the examination. 4. Vertebral endplate osteochondritis dissecans: It is a kind of aseptic inflammation that occurs in the endplate cartilage. Under the stimulation of inflammation, the tissues change and abnormal signals of vertebral body can also appear. The causes of abnormal signals in the vertebral body of cervical vertebrae are many, and it is recommended that further examination be conducted under the guidance of a doctor to clarify the cause of the disease and carry out targeted treatment.
