title: Two cases of subarachnoid hemorrhage from spontaneous anterior cerebral artery dissection : a case of simultaneous hemorrhage and ischemia without aneurysmal formation and another case of hemorrhage with aneurysmal formation.
abstract: Spontaneous anterior cerebral artery (ACA) dissection, although extremely rare, is often associated with severe morbidity and mortality. It could lead to cerebral hemorrhage, ischemic stroke, or, rarely, combination of hemorrhage and ischemia due to hemodynamic changes. Prompt and accurate diagnosis is essential for determining the appropriate management. However, the optimal treatment for ACA dissection remains controversial. Herein, we report on two rare cases of subarachnoid hemorrhage (SAH) caused by ACA dissection; a case presenting with simultaneous SAH and infarction without aneurysmal formation and another case presenting with SAH with fusiform aneurysmal formation. A review of the related literature is provided, and optimal treatments for each type of dissection are suggested.
