Abstract
INTRODUCTION: In our experience, sometimes, the symptom of patients who suffered from infarction in internal capsule (IC) do not necessarily fit the classical fiber distribution. This study aims to explain this phenomenon. METHODS AND MATERIALS: A total of 34 patients with infarction lesions in the IC were included in this study, according to the clinical symptom, divided into three groups, group A (more severe weakness of the foot than the hand), group B (more severe weakness of the hand than the foot) and group C (equal weakness of hand and foot), and group Y (with facial nerve paresis) and group N (without facial nerve paresis). Measurements included the length ratio and the angle degree of infarction lesions compared with the posterior limb of the IC (PLIC).Entities:

“1” means that patient had symptom, “0” means no.
B2 had two lesions in the IC, the total length proportion of two lesion was 0.263–0.81, and between 0.435 and 0.535, there was a gap.
