A long-term cortical blindness after head trauma.

Here is a case of long-term cortical blindness after a head trauma. Its etiology is ascribed to the cerebral vascular occlusion caused by the head trauma. From the findings of both a computerized tomography (CT) and magnetic resonance image (MRI), the lesions of our case are assumed to be in the bilateral areas 17 (Brodmann), some part of the bilateral areas 18, 19 (Brodmann) and bilateral optic radiations. On determination of the areas of these lesions, the location of the lesion in the bilateral areas 17 has been especially done by using the MRI. The MRI findings in our case have a full significance on this point.
