Pure sensory stroke due to bilateral basal ganglion hemorrhage: a case report.

Bilateral simultaneous hypertensive intracerebral hemorrhages are extremely rare. The predisposing factors and pathophysiological mechanisms leading to the development of this picture are not well known. Possible mechanisms of simultaneous multiple hemorrhages include concomitant primary hemorrhages in two or more regions, or development of a second hemorrhage in another region shortly after the primary hemorrhage. The etiology of the cases presenting with bilateral simultaneous basal ganglion hemorrhage include migraine, lightning stroke, hyperglycemic hyperosmolar coma, hypertension and diabetic ketoacidosis coma. Bilateral simultaneous hemorrhage has a poor prognosis. The case of bilateral simultaneous intracerebral hemorrhage presented here had a good clinical course similar to a pure sensorial stroke.
