The common clinical manifestations of spinal cord cavitation, also known as spinal fluid, are water retention and degeneration in the spinal cord due to congenital development and trauma, inflammation, and tumors: Sensory impairment: manifested by loss of temperature and pain sensation in the limbs, patients often complain of different sensations of water temperature, and also when they are treated with hot compresses they are often burned because they do not feel the temperature, and there is no pain after the burn. Limb pain: Patients often show pain in one limb or both limbs, often mistaking it for cervical spondylosis and delaying treatment. Muscle atrophy: Patients exhibit atrophy of the muscles of the upper limbs, mainly the muscles between the palms of the hands, which is then accompanied by contracture and deformation of the fingers. Gradual loss of self-care ability. Walking impairment: As the disease worsens, patients may experience unstable walking, a feeling of stepping on cotton on the soles of the feet, and unstable standing with eyes closed. Concomitant symptoms: The patient may have symptoms of cerebellar ataxia, headache and dizziness. Diagnosis: Patients with these manifestations can be considered for MRI examination. MRI reveals thickening of the spinal cord with the same fluid signal as the cerebrospinal fluid around the spinal cord, which basically establishes the diagnosis and can suggest the cause. Treatment: The treatment of spinal cord cavities is divided into etiologic treatment, which refers to the removal of the cause of the cavity without directly dealing with the cavity, and symptomatic treatment, which refers to the treatment of the cavity. The most common cause of spinal cord cavities is developmental malformation of the craniocervical junction area. Surgery to remove the cause can stop the progression of spinal cord cavities. For the progressive traumatic spinal cord cavity, spinal cord cavity shunt surgery can be performed to divert the fluid in the cavity to the subarachnoid space around the spinal cord or the abdominal cavity through artificial shunts, which can also play a role in protecting the function of the spinal cord.
