ABSTRACT Normal pressure hydrocephalus (NPH) is a treatable neurological condition characterized by dementia, gait disturbances, and urinary incontinence. This case study aimed to evaluate the effectiveness of surgical intervention in treating NPH associated with spinal cord tumors. A patient suffering with NPH underwent a spinal tap procedure and surgical resectioning of three neurinomas on the cauda equina. The patient exhibited marked improvement in neurological and motor symptoms related to NPH following surgical intervention. These findings suggest that surgical resectioning of neurinomas is an effective intervention for treating NPH associated with spinal cord tumors.
