To the best of our knowledge, only 45 cases have been reported to date. We report on a case of a meningioma mimicking an acute subdural hematoma as well as a thorough literature review.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 67-year-old man with no history of trauma was referred to our hospital with sudden onset of decreased level of consciousness and left hemiplegia. Computed tomography revealed an acute convexity subdural hematoma. Emergency surgery to remove the hematoma was performed. The hematoma was found to exist in the extra-axial space and the attached dura mater and pia mater remained intact. Pathological examination revealed a transitional meningioma, the World Health Organization Grade 1. Detailed medical history taken postoperatively revealed that a convexity meningioma had been diagnosed incidentally at another facility 1 year earlier.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Acute subdural hematomas due to meningiomas are rare, and establishing the cause is challenging. Prompt and precise diagnosis of such entities may afford patients a better prognosis.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_328_2020","type":"journal-article","created":{"date-parts":[[2020,8,29]],"date-time":"2020-08-29T06:42:21Z","timestamp":1598683341000},"page":"263","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A convexity meningioma presenting with an acute subdural hematoma"],"prefix":"10.25259","volume":"11","author":[{"given":"Masahiko","family":"Itani","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Shitara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshinori","family":"Akiyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2020,8,29]]},"reference":[{"key":"10.25259\/SNI_328_2020\/ref-1","doi-asserted-by":"crossref","first-page":"150","DOI":"10.1016\/j.wneu.2019.03.248","article-title":"Meningioma presenting with spontaneous subdural hematoma: A report of two cases and literature review","volume":"127","author":"Aloraidi","year":"2019","journal-title":"World Neurosurg"},{"key":"10.25259\/SNI_328_2020\/ref-2","doi-asserted-by":"crossref","first-page":"473","DOI":"10.3171\/jns.2005.103.3.0473","article-title":"Spontaneous intracranial meningioma bleeding: Clinicopathological features and outcome","volume":"103","author":"Bo\u015dnjak","year":"2005","journal-title":"J Neurosurg"},{"key":"10.25259\/SNI_328_2020\/ref-3","doi-asserted-by":"crossref","first-page":"269","DOI":"10.1016\/0303-8467(92)90103-A","article-title":"Meningioma associated with subdural haematoma: Report of two cases and review of the literature","volume":"94","author":"Chaskis","year":"1992","journal-title":"Clin Neurol Neurosurg"},{"key":"10.25259\/SNI_328_2020\/ref-4","first-page":"1","article-title":"Committee of Brain Tumor Registry of Japan.
