Tethered Cord Syndrome (TCS) is a series of clinical signs and symptoms caused by congenital or acquired factors, including dysfunction of urination and defecation, motor and sensory disorders of both lower limbs, physical deformities, pain, etc. Tumors around the spinal cord end filaments and cones (e.g., lipomas, neurinomas, dermoid cysts, etc.) are one of the important components of acquired factors, which can also cause spinal cord tethering. Tumors around the spinal cord end filaments and cones (e.g., lipomas, ventricular meningiomas, nerve sheath tumors, dermoid cysts, etc.) are one of the important components of the acquired factors, which can also cause manifestations of spinal cord embolism.
