Metastasis of neuroblastoma into the central nervous system is well known, but, in fact, rare clinically. Recently we had experienced one such case, which was characterized by sudden onset of paraplegia and blindness and delayed appearance of radiologic findings. A 7 years old Korean boy was admitted to the pediatric ward of the Seoul National University Hospital on September 28, 1975 due to sudden onset of paraplegia. All physical, laboratory and simple thoracic spine X-ray findings were normal except for albuminocytologic dissociation in the C.S.F. Guillain-Barre syndrome was suspected and steroid therapy was recommended. On November 10, 1975, he was readmitted due to sudden loss of visual acuity bilaterally. At first all radiologic examinations revealed no clue to the lesion. After 4 months from the onset, there appeared typical pedicular destruction of the thoracic spine and confirmed it as neuroblastoma by surgery.
