Metastasis to the brain or spinal cord parenchyma is extremely rare in cases of neuroblastoma.We present a 3-year-7-month-old boy with neuroblastoma, stage IV, with intraspinal metastasis. He had no neurologic manifestation except incontinentia urinae and ataxia at the terminal stage. His cranial computed tomography scan showed high density areas in both cerebellar hemispheres which seemed to be distant metastatic masses. At autopsy, the metastases in the cerebellum were found to be due to dural infiltration but in the spinal cord parenchyma of the lumbar spine metastases were detected macroscopically. There were multiple distant metastatic areas near the roots, anterior and posterior. The neuroblastoma seemed to have spread along the roots by direct invasion from the meninges.In the future, the number of patients with metastasis into the brain or spinal cord parenchyma will increase because patients with progressive disease could live for a long time as a result of intensive chemotherapy. Observation of these cases will be helpful to clarify the routes of metastasis to these areas.
