Simultaneous bilateral thalamic hemorrhage: case report.

A 60-year-old man presented with an extremely rare case of simultaneous hypertensive bilateral thalamic hemorrhage manifesting as left hemiparesis with headache followed by deterioration in consciousness and tetraparesis. CT scan confirmed the bilateral thalamic hemorrhages 17 hours after onset. Magnetic resonance imaging showed the bilateral thalamic lesions had similar signal intensities, consistent with the simultaneous onset, and had no evidence of hemorrhagic reason. Conservative treatment achieved some neurological improvement, but he died of pneumonia six months after onset. The prognosis of a patient with bilateral hemorrhages is worse than would be indicated by the size of the hemorrhages.
