Temporary Ventriculo-Peritoneal Shunt Malfunction in Normal Pressure Hydrocephalus

Abstract

Normal-pressure hydrocephalus (NPH) may be defined as a state of chronic hydrocephalus in which the prevailing Cerebrospinal Fluid (CSF) pressure has returned to a physiologic range but in which a slight pressure gradient persists between the ventricles and brain. 63-year-old man who was complaining of dementia, incontinence and a disturbance of gait was admitted with the diagnosis of NPH. V-P shunt was placed in 1992. He recovered soon after the shunt insertion, however 8 years after, he start having the same complains that he also had ventricular dilation on CT. He recovered spontaneously in a month both clinically and radiologically. We discussed the temporary V-P shunt malfunction besides the clinical presentation and radiological findings of NPH in this article.
