A case is reported of anterior cerebral artery dissecting aneurysm presenting with subarachnoid hemor-rhage and cerebral infarction. A 50-year-old man presented with sudden onset of weakness of the left low-er limb was admitted to our hospital. CT scan on admission showed a subarachnoid hemorrhage ln the in-terhemispheric fissure and CT on the 6th day demonstrated a cerebral infarction on the right medial fron-tal lobe. A carotid angiogram 12 hours after the onset showed no aneurysmal leslon, but, the angiogram re-peated 11 days after the onset revealed an aneurysmal dilatation with distal narrowing at the right A2-A3 segment.
