What are the symptoms of cone tube tumors? Let's talk about it

Symptoms of conotruncal tumors

Intramedullary tumors mostly occur in 20-50 years old, with pain as the most common first symptom, and gradually appear dyskinesia and sensory abnormalities below the tumor segment, manifested as limb weakness, muscle atrophy and paraplegia, abnormal muscle tension and tendon reflex.

Extramedullary intradural tumors mostly occur in 20-60 years old, with a long course of disease. The typical symptoms are nerve root pain, and then limb numbness, acid swelling or hypoesthesia. With the progress of symptoms, paralysis and dysfunction of bladder and rectum may appear.

Extramedullary and epidural tumors, such as metastases, are more common in the elderly. The course of disease progresses rapidly. Pain is the most common first symptom, and severe spinal cord compression occurs soon. Lymphoma often involves the thoracolumbar spine, mainly manifested as spinal cord and nerve root compression symptoms, with local pain most common, and gradually appear lower limb movement, sensory disorders and sphincter dysfunction.
