The rete middle cerebral artery (MCA) is a rare entity causing hyperdynamic blood flow into the ipsilateral anterior cerebral artery (ACA), especially when the contralateral A1-segment is non-dominant. Ruling out the clinicoradiological mimics like vasculitis, moyamoya and chronic occlusive disease with vessel wall imaging and detailed investigations helps manage the clinical entity effectively. We present a successfully managed case of ruptured ACA aneurysm at the acute curvature of the A1\u2013A2 junction associated with ipsilateral rete MCA. Pre-emptive diagnosis of the rete MCA can aid preventive strategies to manage rupture and regrowth of the aneurysm at the points of flow-related stress.<\/jats:p>","DOI":"10.1136\/bcr-2020-240219","type":"journal-article","created":{"date-parts":[[2021,2,1]],"date-time":"2021-02-01T17:20:28Z","timestamp":1612200028000},"page":"e240219","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Rete
