[Large kissing aneurysms of the middle cerebral artery: a case report--classification of kissing aneurysms].

We report a rare case of kissing aneurysms located at the middle cerebral artery. A 69-year-old man had a severe subarachnoid hemorrhage associated with intracerebral hematoma (Hunt and Hess grade 5, WFNS grade V). Angiography revealed two large-sized aneurysms of the middle cerebral artery, and these aneurysms were seen as contacting each other.
