Bilateral simultaneous hypertensive intracerebral hemorrhages (HICH) are a rare occurrence. Computed tomography (CT) enables us to diagnose such a condition which is difficult to recognize clinically. In the series, six patients (2.6%) from a series of 553 HICH cases had suffered from simultaneous rehemorrhage in the contralateral hemisphere. It comprised four males and two females. Their ages ranged from 54 to 64 years with a mean age of 58 years. The clinical symptoms were excessively sever and were characterized by severe consciousness disturbance (semicoma to coma, 6 cases), aphasia (5 cases) and bilateral paresis (3 cases). CT density profiles were identical, implying that the hematomas were of similar age but located areas; two were bilateral basal ganglia, one was bilateral specular thalamus, pontine-ganglia (right), thalamo (left)-ganglia (right) and occipito (right)-thalamus (left) individually. All of the hematomas had ruptured into the ventricles. The predominant sites of hemorrhage were in the putamen (50%, 6/12) and the thalamus (33%, 4/12). Two patients received emergency craniotomy for evacuation of the hematomas. However, they died soon after the operations. In the remaining four non-surgical cases, two died of central failure, another died of pneumonia and the remain one survived but retained hemiplegia sequelae. The serious surgical results and outcome in bilateral HICH was compared that of unilateral HICH. Hemodynamically, poor cerebral blood flow and diaschisis phenomenon may contribute to the poor prognosis in these patients.
