title: Disc swelling: a tall tail?
abstract: A 30-year-old man presented with monocular visual loss secondary to chronic papilledema, due to an ependymoma involving the spinal cord. No other neurological symptoms were present at the time. Initial neuroradiologic tests as well as laboratory investigations were negative, except for elevated pressure and protein concentration of his cerebrospinal fluid. In spite of intensive investigation, the diagnosis of a spinal cord tumor was delayed for approximately 12 months until he presented with neurologic symptoms attributable to a spinal cord lesion. This is only the fourth case reported of a spinal cord tumor associated with papilledema presenting with visual loss, without any other manifestations of either elevated intracranial pressure, or spinal disease. Possible mechanisms for elevated intracranial pressure in cases of spinal cord tumors are reviewed.
