title: [Electrophysiologic study in a patient presenting with expanding cerebral lacunae].
abstract: A 42-year-old man was affected with multiple cerebral lesions suggesting expanding lacunae. He had suffered for about 15 years of headaches and blurred vision. Neurological examination showed a Parinaud syndrome and a skew deviation. Magnetic resonance imaging showed an enlargement of the third and lateral ventricles and multiple intraparenchymatous lesions with a signal similar to that of the cerebrospinal fluid. These lesions were located in the mesencephalon and right thalamic region. Important discrepancies between the topography of the lesion and the clinical data were observed. Neurological examination, ocular movements during wake and neuropsychological testing suggested sub-cortical dysfunction. These results suggest functional rather than lesional repercussion of expansive lacunae.
