Cervical disc hyposignalization is generally a condition in which a cervical disc undergoes degenerative changes and appears to have a reduced signal on an MRI. As cervical discs age, degenerative changes usually occur, including loss of elasticity of the nucleus pulposus, loss of water, and wear and tear of the annulus fibrosus, which can result in a reduced signal on the MRI. In the early stage of cervical disc degeneration, there are usually no obvious symptoms, but as the disease worsens, neck and shoulder pain, upper limb pain and numbness will occur, and in severe cases, lower limb dysfunction and urinary and fecal dysfunction will also occur. When cervical disc signal reduction occurs, it is recommended to go to the hospital in time for early treatment to minimize the adverse effects of the disease.
