title: [Associated meningioma and neurofibroma at the same cervical level without clinical signs of neurofibromatosis: case report].
abstract: A 59-year-old woman presented with a history of progressive clumsiness and numbness in both hands. MRI suggested a solid mass extending, from the intradural extramedullary, extradurally at the left C1/2 level. However, intraoperative findings revealed the both the intradural tumor and the extradural tumor existed separately. Histopathological findings revealed coincident meningioma (intradural) and neurofibroma (extradural). These lesions were not associated with neurofibromatosis, and the patient did not have other tumors in either the brain or at other levels of the spine. The occurrence of different types of spinal tumors without clinical signs of neurofibromatosis is very rare. Only five cases have been reported in the literature. To our knowledge, this is the first case of occurrence of different types of spinal tumors at the same level.
