The magnetic resonance revealed an 18-mm tumor ventral to the foramen magnum that significantly enlarged over the past 6 months. She underwent total tumor resection but then presented with progressive HC both clinically (i.e., instability of gait with confusion) and radiographically (computed tomography). Following placement of a lumboperitoneal (LP) shunt, symptoms markedly improved. Further, the cerebrospinal fluid (CSF) analysis showed elevated cell counts and protein concentrations, indicating likely \u201cleakage\u201d of intratumoral contents postoperatively contributing to the progressive HC.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Patients presenting with acute meningiomas ventral to the foramen magnum may develop postoperative communicating HC attributed to tumor-related CSF leakage of necrotic intratumoral components that can be successfully treated with a LP shunt.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_129_2024","type":"journal-article","created":{"date-parts":[[2024,7,5]],"date-time":"2024-07-05T09:08:25Z","timestamp":1720170505000},"page":"231","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Communicating hydrocephalus after resection of a meningioma ventral to the foramen magnum"],"prefix":"10.25259","volume":"15","author":[{"given":"Kowashi","family":"Taki","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Osaka University Hospital, Suita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koshi","family":"Ninomiya","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Osaka University Hospital, Suita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiro","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Osaka University Hospital, Suita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takuya","family":"Suematsu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Osaka University Hospital, Suita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manabu","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hanwa Memorial Hospital, Osaka, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haruhiko","family":"Kishima","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Osaka University Hospital, Suita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2024,7,5]]},"reference":[{"key":"10.25259\/SNI_129_2024\/ref-1","doi-asserted-by":"crossref","first-page":"ons58","DOI":"10.1227\/01.NEU.0000382971.63877.DD","article-title":"Management of anterolateral foramen magnum meningiomas: Surgical vs. conservative decision making","volume":"67","author":"Benoit","year":"2010","journal-title":"Oper Neurosurg"},{"key":"10.25259\/SNI_129_2024\/ref-2","doi-asserted-by":"crossref","first-page":"E9","DOI":"10.3171\/2011.3.FOCUS117","article-title":"Predicting postoperative hydrocephalus in 227 patients with skull base meningioma","volume":"30","author":"Burkhardt","year":"2011","journal-title":"Neurosurg Focus"},{"key":"10.25259\/SNI_129_2024\/ref-3","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1055\/s-2000-9331","article-title":"Postoperative hydrocephalus in cranial base surgery","volume":"10","author":"Duong","year":"2000","journal-title":"Skull Base Surg"},{"key":"10.25259\/SNI_129_2024\/ref-4","doi-asserted-by":"crossref","first-page":"406","DOI":"10.4103\/jcvjs.jcvjs_58_21","article-title":"Foramen magnum meningioma: Series of 20 cases.
