Spinal Cord Cavernous Disease is a slowly progressive degenerative disease of the spinal cord. It is characterized by the formation of a cavity in the central part of the spinal cord due to different causes, which leads to the typical clinical symptoms: loss of pain and temperature sensation at the segmental level, and muscular atrophy and trophic deficits in the area innervated by the lesion. If the lesion invades the brainstem, it is called medullary cavernous disease, also known as bulbar cavern. Clinically, it is characterized by the loss of pain and temperature sensation and the preservation of deep sensation, and is accompanied by motor and neurotrophic disorders caused by damage to the long tracts of the spinal cord. Patients are often found to be ill only after their arms have been burned, cut or stabbed without knowing the pain, and are often accompanied by spontaneous pain, numbness, ankylosis and other sensory abnormalities in the hands and arms. When examined, it can be seen that the pain and temperature sensation on one side or both sides of the spinal cord according to the segmental distribution is obviously retarded or disappeared, while the sense of touch is retained or mildly impaired, and its scope usually extends up to the neck and down to the chest, showing a shawl or a short blouse-like distribution. If the cavity affects the trigeminal sensory bundle of the upper cervical medulla, pain and temperature sensory deficits may also occur in the face. If the cavity begins in the lumbosacral region, there is a detached superficial sensory deficit in the lower extremities and perineum. If the hole reaches the posterior root entrance, all superficial and deep sensations in the damaged segment may be lost. Bundle sensory deficits. When the cavity extends to damage one or both thalamic tracts of the spinal cord, it produces fascicular superficial sensory deficits on the contralateral or bilateral trunks below the level of damage. The posterior cord of the spinal cord is often the last to be damaged, and deep sensory deficits occur in the ipsilateral or bilateral trunks below the level of damage. The shape and distribution of the cavities are often irregular, and segmental and fascicular sensory deficits are often mixed. At present, there is no specific treatment. Radiation therapy is often used to treat the spinal cord lesions, but the efficacy is very uncertain. Physical therapy should be given to the affected joints and muscles to prevent joint deformity. Care should be taken to prevent lung and urinary tract infections. Analgesics (or nerve blockers such as thiamphenicol), B vitamins, ATP, coenzyme A, inosine, etc. may be continued.
