title: Normal pressure hydrocephalus caused by a spinal neurinoma at the cauda equina level: a case report.
abstract: Neurinomas are common space-occupying lesions located in the spinal canal. Many reports concerning their clinical characteristics, diagnoses, treatments, and operative results have been published. Some case reports have discussed spinal neurinomas located at the cauda equina level. However, there is little information on their natural history. Here, we report a case of spinal neurinoma located at the cauda equina level, which caused normal pressure hydrocephalus (NPH). All symptoms resulting from the NPH were resolved by tumor removal. These findings suggested that if a spinal neurinoma located at the cauda equina level causes symptoms due to NPH, then removal of the tumor should be considered, when appropriate removal procedures are possible.
