Normal-pressure hydrocephalus due to tentorial meningioma.
Normal-pressure hydrocephalus and the associated triad of dementia, apraxic gait and urinary incontinence may be casued by various, sometimes unsuspected, lesions, usually those that block the flow of cerebrospinal fluid (CSF) around the tentorium. A 58-year-old woman with insidious onset of behaviour and gait problems had occult, normal-pressure hydrocephalus and a tentorial meningioma, resection of which produced complete recovery. This case demonstrates that a distinction must be made between the syndrome of normal-pressure hydrocephalus resulting from disturbance in CSF dynamics and the pathophysiologic features of the underlying lesion.
