[Development of papilledema in cases of tumors of the lower segment of the vertebral canal].
The author discusses the problem of the mechanism of intracranial hypertension developing with papilloedema in cases of tumours situated in the lower parts of vertebral canal. The author discusses the present data in literature and an own case in which manifestations of intracranial hypertension with papilloedema developed in a 48-year-old man with neuroma situated in the vertebral canal at the level of 11th thoracic vertebra. In a discussion on the problem the author stresse that his case failed to confirm the accepted view that the cause of intracranial hypertension in cases of tumours in the lower part of the vertebral canal should be sought in increased protein level in the cerebrospinal fluid. Attention was called also to the fact that in most cases described as yet presence of gliomas was demonstrated and the cerebrospinal fluid pressure was never so high (700 mm H2O in lying position).
