title: Neuroblastoma presenting as central nervous system disease.
abstract: Neuroblastoma may be extremely difficult to recognize, particularly when the tumor presents as a primary central nervous system disease. Central nervous system involvement may be considered as primary intracerebral neuroblastoma, metastases to the cranium from an occult primary, primary intraorbital neuroblastoma originating in the ciliary ganglion, metastatic intraorbital neuroblastoma from an occult primary, primary intraspinal neuroblastoma originating in dorsal root ganglia, intraspinal metastatic disease, and distant effects such as myoclonic encephalopathy. Primary neuroblastoma within the ciliary ganglion and primary intraspinal neuroblastoma are extremely rare entities. Illustrative cases the demonstrate the broad spectrum of neurologic presentations are offered. The second known report of neuroblastoma in association with primary pulmonary hypoventilation (Ondine curse) is included.
