Clinicoradiological study on 59 patients with pure motor hemiparesis due to corona radiata infarcts

Abstract

To evaluate the clinicoradiological findings of patients with small infarction at the level of the corona radiata, such patients were divided into three groups: Group A (facio-lingual weakness), Group B (arm-dominant weakness) and Group C (leg-dominant weakness). The anteroposterior position and maximum diameter of the radiata infarcts were assessed by axial T2-weighted imaging. In total, 59 consecutive patients (42 men and 17 women) were selected. The frequency of radiata infarct is 9.4% among cerebral infarct patients. The male/female ratio was 1.3. The mean age (SD) was 68.9 (9.5) years. The number of patients was 23 in Group A, 19 in Group B and 17 in Group C. Group B patients needed aid in their daily life, when compared to Group A and Group C. The cerebrovascular risk profiles demonstrated hypertension in 43 patients (72.9%), diabetes mellitus in 15 (25.4%), current smoking in 22 (37.3%), dyslipidemia in 16 (27.1%) and arterial fibrillation in 11 (18.6%). The clinical subtypes revealed 48 patients with lacunar infarct and 11 with cardiogenic emboli. The somatotopical distribution of motor fibers of Groups A to C was arranged in antero-posterior order. There were 24 patients with right lesions and 35 with left lesions. The size of the  More>>

There were 24 patients with right lesions and 35 with left lesions. The size of the left infarcts was significantly smaller than that of the right infarcts. The clinical outcome of patients with arm-dominant weakness was relatively poor as compared to that of patients with dysarthria or leg-dominant weakness. The neuroradiological data suggest that left radiata infarct is smaller and more frequent than right infarct. (author)}
