    Abstract:
    Increased intracranial pressure and papilledema are occasionally observed in patients harboring spinal tumors in the cervical region or at the craniocervical junction, and the mechanical obstruction to the cerebrospinal fluid circulation is assumed to be responsible for such symptoms and signs. However, increased intracranial pressure is very rare in spinal tumors locating in the dorso-lumbar region; only 44 such cases having been reported in the literature. Recently we saw a 58-year-old female who presented with three brief episodes of loss of consciousness associated with nausea and vomiting, progressive dementia and insomnia. Neurologic examination disclosed an early papilledema, weakness of both legs and dementia. A left carotid angiogram revealed a small aneurysm arising from C2 segment of the internal carotid artery. Right carotid and bilateral vertebral angiograms were not contributory. The aneurysm was clipped at the first operation. The aneurysm was found apparently unruptured. A ventriculoperitoneal shunt failed to improve her dementia. Finally, a total myelographic block was found at L1 level, and a neurinoma arising from the right D12 was removed. After this, all symptoms and signs disappeared within 3 weeks. Pertinent literature on the low spinal cord tumor associated with an intracranial pressure was reviewed and the mechanism of the elevation of intracranial pressure in such cases were discussed.
