[Bilateral parietal syndrome approximating a Balint syndrome].
A patient presented with disorders of saccadic and pursuit movements a wandering gaze, the impossibility to maintain fixation, a concentric shortening of visual attention mainly of the right side, an incomplete right homonymous hemianopia (respecting 10 to 20 degrees), and optical and auditory ataxia predominantly affecting the right hand. Pathology showed a large left parietal glioma in the white matter in the superior and inferior parietal lobes, with microscopic evidence of parietal cortex invasion. A hematoma on the right side was situated entirely parasagitally in the precuneus, approaching the cortex at this level. The two lesions were independent and the splenium was intact. The frontal lobes were normal. A review of nearly 30 cases of bilateral syndrome of the parieto-occipital junction showed that anomalies of visually guided ocular movements were always present. These cases require differentiation from those, such as the present case, which involve mainly a visuomotor coordination disorder and from those with predominant visual disorientation.
