A retrospective analysis was carried out on 52 patients with CT-identified lacunar infarcts in order to identify possible risk factors. It was found that arterial hypertension, cardiac emboli and/or emboli from epiaortic vessels play a significant role in the genesis of lacunar infarcts. No preferential relationship was found between "small" lacunes and(More)
The authors report the cases of two patients with CT-documented paramedian mesencephalo-thalamic infarcts, showing language disturbances. The first patient showed a non fluent, transcortical motor-like aphasia, the other had a fluent but severely paraphasic language disorder. The CT study disclosed that it was the dorso-median thalamic nucleus that was(More)
We studied 80 patients with lacunar strokes in the attempt to find a relation between lacunar strokes, arterial hypertension and leucoaraiosis. Leucoaraiosis was found in 47 patients (58,75%) on CT-scan. Our findings emphasize that arterial hypertension is the most important risk factor of leucoaraiosis (p less than 0.003); but we did not find a relation(More)
We describe the case of a right-handed, 83 year-old woman with CT-documented left frontal subacute subdural hematoma showing reversible right-sided hemiparesis and aphasia. We discuss possible pathogenetic mechanism for this unusual condition and emphasize that the clinical evaluation cannot always distinguish ischemic causes for certain. Therefore CT-scan(More)
We describe two patients in whom CT brain scans imaged paramedian thalamo-subthalamic infarcts in the territory of the thalamo-mesencephalic arteries. Such infarcts give rise to a complex syndrome marked by disturbances of consciousness and of eye movement and neuropsychological disorders, including attentional, memory and, more rarely, language deficits.
