SPONTANEOUS REGRESSION OF INTRASPINAL NEUROBLASTOMA

In two infants aged 5 days and 2 months paresis of the legs due to spi nal cord compression by a dumbbell neuroblastoma suddenly appeared. Im mediate surgical resection of only the paraspinal tumor mass was perfo rmed. Without any further treatment, prompt spontaneous regression of the intraspinal component occurred, and the paresis disappeared within 2 weeks in both infants. We advocate surgical excision of the paraspi nal tumor mass as the sole treatment in infants with symptomatic dumbb ell neuroblastoma.
