There has been considerable controversy concerning divergence paralysis, an entity described as early as 1883 by Parinaud. We recently observed a patient with divergence paralysis, who on CT scan presented a small hematoma in the tegmentum of the brainstem. This case may support the theory that the center for divergence exists in the upper brainstem.
