Esthesioneuroblastoma: cerebral and spinal metastases without direct cranial invasion.

A patient with esthesioneuroblastoma is reported with metastatic lesions to the cervical nodes, intradural thoracic spinal canal, and the posterior fossa without evidence of local recurrence or cranial bone involvement four years after initial diagnosis and eradication. The initial lesion was a localized nasal polyp apparently treated adequately with excision and radiotherapy.
