Clinical and computerized tomographic study of hypertensive intracerebral hemorrhage.

Historical, neurological, and computerized tomographic findings were correlated in 32 patients with hypertensive intracerebral hemorrhage. The mortality figures given in standard texts appear to be too high; the more acceptable figure would seem to be approximately 40%. Special attention was given to intraventricular rupture, which complicated 62% of the cases. Sudden onset of coma appears to correlate with the presence of intraventricular rupture. The "ring sign," if looked for, will be seen in most cases of resolving intracerebral hematoma.
