Although this condition is usually discovered incidentally during prenatal or neuroimaging examinations, its clinical significance and long\u2010term effects are still being studied and discussed. The prognosis and treatment of MCM depend on its differentiation from other posterior fossa malformations, including Blake\u2019s pouch cyst, Dandy\u2013Walker variant, and arachnoid cysts. In addition to exploring debates surrounding MCM and potential clinical applications, this review attempts to summarize the state of knowledge currently available on the anatomical, embryological, clinical, and radiological aspects.<\/jats:p>","DOI":"10.1155\/rrp\/9591364","type":"journal-article","created":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T06:50:03Z","timestamp":1763967003000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Mega Cisterna Magna: Current Perspectives and Future Directions\u2014A Literature Review"],"prefix":"10.1155","volume":"2025","author":[{"given":"Masoud","family":"Pishjoo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0296-368X","authenticated-orcid":false,"given":"Daniel","family":"Kheradmand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Safdari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zohre","family":"Safdari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mojtaba","family":"Mashhadinejad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,23]]},"reference":[{"key":"e_1_2_17_1_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-007-0369-6"},{"key":"e_1_2_17_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/pd.5046"},{"key":"e_1_2_17_3_2","unstructured":"GafnerD.
