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.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 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\u2019s 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.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nBefore the placement of shunts for NPH, patients should undergo holospinal MR imaging studies to rule out attendant spinal intradural extramedullary tumors.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_624_2022","type":"journal-article","created":{"date-parts":[[2022,8,12]],"date-time":"2022-08-12T05:47:15Z","timestamp":1660283235000},"page":"352","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cerebrospinal
