Xuejun Li, Department of Neurosurgery, Xiangya Hospital, Central South University, replied: Hello! The main concern is the possibility of spinal cord embolism. To provide some general knowledge of the disease: the spinal cord rises to the adult level after 3 months of life, i.e., the end of the cones are at the L1 level. The spinal cord cones are thinned and shifted to the end filaments (less than 2 mm in diameter in adults). In the process of upward movement of the spinal cord, if there are pathological changes such as spinal cord pulling due to incomplete closure of the neural tube, intravertebral lipoma, spinal cord cone dermatoid cyst or teratoma, longitudinal fissure of the spinal cord, etc., the fixation of the distal end of the spinal cord and the nerve roots is effected by the pathology of the lesion. Be careful if symptoms such as lumbosacral skin abnormalities (sacrococcygeal lipoma, etc.)/pain/bladder and rectal dysfunction/sensory disorders/motor dysfunction/musculoskeletal malformations are present. Xuejun Li, Department of Neurosurgery, Xiangya Hospital, Central South University, suggests regular follow-up and no need to consider surgery for the time being. Good luck!
