[Simultaneous multiple hypertensive intracerebral hematoma].
Hypertensive intracerebral hemorrhage (HIH) occurring simultaneously in different locations is rare. We encountered 11 such cases between January 1990 and November 2002. The diagnosis of all 11 cases was established by computed tomography, and the location of the hematomas was: cerebellum and basal ganglia in 5 cases, pons and basal ganglia in 4, and subcortex and basal ganglia in 2. Our patients were analyzed with respect to clinical characteristics, pathogenesis of multiple hematomas, and indication of operation. These patients represented 1% of all 1,069 patients we encountered with HIH. As past history, there were no characteristic disorders except hypertension. There were no characteristic initial symptoms suggesting that hemorrhage had occurred simultaneously. Both supra- and infra-tentorial hematomas were observed in 80% of the patients, and the size of the multiple hematomas was proportional in principle. Cerebellar hematomas were often mild, and pontine hematomas were often severe. The outcome in those patients whose neurological grading was 1 to 3 was good with conservative therapy or surgical treatment. The severity, treatment methods, and outcomes in these patients were similar to those in patients with single HIH, which suggests only a slight influence of multiple lesions on outcome. As for the possible mechanism of simultaneous multiple hemorrhages, we speculated that bleeding occurred simultaneously in the different regions, or that the initial bleeding was followed after a short time by secondary bleeding due to high intracranial pressure and circulatory disturbance. In patients with cerebellar hematoma, initial symptoms suggested the development of secondary hemorrhage after primary hemorrhage. The surgical treatment for multiple hematomas should be determined by the location and maximum axis of the hematoma. We proposed that cerebellar hematomas should be removed if the supra-tentorial hematoma is small.
