The presentation, treatment, clinical course, and outcome of identified cases are compiled. In addition, a patient suffering from an infratentorial SDH following aneurysm rupture is presented with an illustrative case.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nThree articles were identified and met inclusion criteria. All cases occurred from ruptured posterior communicating artery aneurysms. All patients arrived with a Hunt and Hess classification of 2 or less. Only one case was managed with operative aneurysm clipping and hematoma evacuation while the other three cases were managed endovascularly. There were no reported postoperative complications, vasospasm, or seizures reported. All patients had a final Modified Rankin score of 3 or less at last reported follow-up.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nInfratentorial AnSDH without associated SAH is an etiology rarely reported in the literature. Here, we present a case report and systematic review demonstrating a relatively benign clinical course and outcome compared to report aneurysm rupture associated with SAH or mixed SAH and SDH. Moreover, there appear to be lower rates of vasospasm and improved outcomes in patients with isolated AnSDH compared to the literature aneurysmal SAH rates.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_758_2022","type":"journal-article","created":{"date-parts":[[2022,10,28]],"date-time":"2022-10-28T08:34:06Z","timestamp":1666946046000},"page":"499","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Infratentorial
