Caudate hemorrhage.

We studied 12 patients with intracerebral hemorrhage in the head of the caudate nucleus. These cases accounted for 7% of a consecutive series of intracerebral hemorrhage. The clinical findings differed from more common varieties of supratentorial hemorrhage. All patients had acute onset of vomiting, headache, stiff neck, decreased level of consciousness, and behavioral changes in a pattern that simulated subarachnoid hemorrhage. Seven patients had gaze paresis and hemiparesis, with or without sensory loss. Two of these seven patients had, in addition, elements of Horner's syndrome. The prognosis for recovery was good. No patient had recurrent hemorrhage or persistent hydrocephalus.
