“…[7] Notably, most of their tumors occur in the lumbar spine, with two cases being found in the cervical region. [5][6][7] Cause of NPH with spinal tumors ere are several considerations regarding the cause of NPH with spinal tumors. [2,4,7] An increase in tumor-related CSF protein likely contributes to an aseptic arachnoiditis and adhesions, resulting in poor CSF flow resulting in reflux and hydrocephalus.…”

“…[7] In four cases, including ours, NPH shunting performed before tumor removal resulted in the rapid progression of spinal cord deficits over an average period of just 4.3 postoperative months [Table 1: cases 1, 2, 3, and 4]. [5,6] We, therefore, conclude that NPH shunting be avoided before spinal tumor removal to avoid exacerbating tumor-related spinal cord deficits; further, symptoms spontaneously resolve following tumor excision alone without shunting in the majority of these patients.…”

Background: Normal-pressure hydrocephalus (NPH) and spinal intradural extramedullary benign tumors rarely exist together. Here, a 72-year-old female who presented with NPH symptoms (i.e., gait disturbance and dementia) newly developed symptoms of spinal cord compression attributed to a previously undiagnosed schwannoma. Case Description: A 72-year-old female was diagnosed with NPH without disproportionately enlarged subarachnoid space hydrocephalus. The lumbar puncture revealed an elevated cerebrospinal fluid (CSF) protein level of 0.141 g/dl, but with normal pressure. The patient’s NPH symptoms improved after lumbar-peritoneal shunt placement. However, a year later, she subacutely developed a progressive Brown-Sequard syndrome. On the cervical magnetic resonance (MR), an intradural extramedullary lesion was found at the C5-C6 level which at surgery, proved to be a schwannoma. A review of this patient and three others with NPH and intradural extramedullary benign tumors revealed that 4.3 months following CSF shunting for NPH, they developed rapidly progressive cord deficits, attributed to their benign spinal tumors. Conclusion: Before the placement of shunts for NPH, patients should undergo holospinal MR imaging studies to rule out attendant spinal intradural extramedullary tumors.
