[Binswanger's subcortical encephalopathy. Study of a case with predominant left hemispheric lesion (author's transl)].

We report the clinical and pathological study of a patient with vascular leucoencephalopathy almost restricted to the left posterior hemisphere. A 65 year--old right handed hypertensive woman has presented with a neuropsychological symptomatology of transcortical sensorial aphasia. We discuss the following points: 1) the patient's disease must be considered as Binswanger's subcortical encephalopathy despite the asymetric topography of the lesions ; 2) particular hemodynamic cerebral factors has possibly determined the asymetric nature of the disease ; 3) a lesion of the left temporo-parieto-occipital area that was strictly sub-cortical, with complete destruction of the posterior part of the arcuate fasciculus has presented with the clinical picture of a transcortical sensorial aphasia.

[Arterial vascularization of the retrochiasmatic optic tract in man: recent data].

The authors study the arterial vascularisation of the retro chiasmatic optic tracts in man by means of total or selective arterial injections on 200 brain specimens. They underline the important vascularisation of the optic tracts, the lateral geniculate body and the first part of the optic radiations contrasting with the precarious vascularization of the latero-ventricular part of the optic radiations. The importance of the Sylvian contribution is noted at the origin of the optic radiations and on the occipital cortex level.

[NEOLOGISMS AND MOTOR APHASIA. (Afferent pathology?)].

The authors describe a case of post-traumatic aphasia in a 39-year-old man. The linguistic disturbances were marked by the unusual association of oral expression consisting mainly of neologisms, normal comprehension and almost normal written expression. A physiological interpretation based on disturbance of treatment of the sensory afferent nerves from the bucco-phonator organs is suggested to account for the neologisms in this particular form of aphasia.
