Various treatments have been proposed, including wrapping, clipping with or without cortical resection, and coil embolization, but there is no consensus on the best approach.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>We present a case of a 69-year-old female who experienced olfactory hallucinations caused by a posterior communicating artery aneurysm and was treated with clipping without cortical resection, with a positive outcome.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>According to our knowledge, there has been only one report of a posterior communicating artery aneurysm presenting with olfactory hallucinations has been reported, where clipping and cortical resection were performed. This is the first report of a posterior communicating artery aneurysm with olfactory hallucinations that was effectively treated with clipping alone. There have been a few similar reports of large middle cerebral artery aneurysms, most of which are believed to be caused by entorhinal cortex compression. Although a definitive treatment protocol for this condition remains elusive, we suggest that elimination of the pulsatile compressive stress exerted on the cerebral cortex through surgical clipping or coil embolization is crucial for achieving efficacious seizure management.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_173_2023","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T08:51:17Z","timestamp":1682671877000},"page":"152","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Olfactory hallucinations caused by an unruptured posterior communicating artery aneurysm improved by clipping: A case report with literature review"],"prefix":"10.25259","volume":"14","author":[{"given":"Shimpei","family":"Tsuboki","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Japanese Red Cross Kumamoto Hospital, Kumamoto City, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatemi","family":"Todaka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Japanese Red Cross Kumamoto Hospital, Kumamoto City, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shu","family":"Hasegawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Japanese Red Cross Kumamoto Hospital, Kumamoto City, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuyuki","family":"Kaku","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kumamoto University Hospital, Kumamoto City, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Ohmori","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kumamoto University Hospital, Kumamoto City, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akitake","family":"Mukasa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kumamoto University Hospital, Kumamoto City, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2023,4,28]]},"reference":[{"key":"10.25259\/SNI_173_2023\/ref-1","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1212\/WNL.51.1.56","article-title":"Olfactory epileptic auras","volume":"51","author":"Acharya","year":"1998","journal-title":"Neurology"},{"key":"10.25259\/SNI_173_2023\/ref-2","doi-asserted-by":"crossref","first-page":"197","DOI":"10.4103\/sni.sni_134_17","article-title":"A case of unruptured aneurysm of the internal carotid artery presenting as olfactory hallucinations","volume":"8","author":"Akimoto","year":"2017","journal-title":"Surg Neurol Int"},{"key":"10.25259\/SNI_173_2023\/ref-3","doi-asserted-by":"crossref","first-page":"173","DOI":"10.1093\/brain\/94.1.173","article-title":"Clinical course and prognosis of temporal lobe epilepsy.
