Anterior cerebral artery dissection (ACAD), especially simultaneously presenting with subarachnoid hemorrhage (SAH) and cerebral infarction (CI), is rare. Only a few cases of severe SAH due to ACAD have been reported. Herein, we present an unusual case of severe SAH with simultaneous CI caused by ACAD. A 56-year-old male was brought to our hospital for severe disturbance of consciousness. Head computed tomography (CT) disclosed SAH with intracerebral hematoma. We suspected ruptured anterior communicating artery saccular aneurysm on CT angiography. Emergency craniotomy was performed to avoid cerebral herniation which confirmed the ruptured ACAD of right A2. The dissecting site was treated by wrapping with a Goretex sheet. ACAD of A2 may present with a severe hemorrhagic event.
