Aneurysm formation on collaterals is common. The rupture of these aneurysms is associated with a poor prognosis, which presents significant treatment challenges.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st2\">\n                    <jats:title>Case Description:<\/jats:title>\n                    <jats:p>We encountered two cases of distal choroidal artery aneurysm rupture in MMD. The first case experienced re-rupture and underwent superselective embolization. However, this case was complicated by an intraoperative rupture and subsequent hydrocephalus. The second case underwent parent artery occlusion without complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st3\">\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>These cases highlight both efficacy and the risks involved.
