The Clinical Syndrome of Aneurysm of the Middle Cerebral Artery

The clinical syndrome of aneurysm of the middle cerebral artery is poorly defined. Though many cases of aneurysm of this artery have been recorded, they represent for the most part instances in which the aneurysm has been found at autopsy. Clinical correlations have been notably lacking. For this reason, we have analyzed 12 cases of aneurysm of the middle cerebral artery verified at operation or autopsy in order to define the clinical syndrome and to determine, if possible, the criteria whereby the diagnosis may be established before rupture. REPORT OF CASES Case 1.— J. M.; No. LH 2240. History.— The patient, a 48-year-old white married man, was admitted to the St. Luke's and Children's Medical Center on April 19, 1948, because of a generalized convulsion, followed by weakness of the right leg and severe, constant, throbbing headache, which was most prominent in the occipital region.
