Striatocapsular infarction is known to have various neurologic manifestations including cortical symptoms. However, striatocapsular infarction patients without cortical dysfunctions can be easily found. Therefore, we tried to evaluate the properties and pathogenesis of two distinct expressions of striatocapsular infarction, striatocapsular infarction with and without cortical dysfunctions respectively. Forty‐eight patients were divided into two groups according to their initial manifestations. Forty‐eight patients with striatocapsular infarction were divided into cortical type of striatocapsular infarction (CSCI) and non‐cortical type (NCSCI) according to their initial manifestations. We compared the properties such as stroke risk factors, laboratory data, and clinical features and assessed magnetic resonance imaging (MRI) and MR angiography for possible mechanisms in each type of striatocapsular infarction. Patients with CSCI and those with NCSCI had similar characteristics, laboratory data and morphologic findings in MRI. CSCI patients had more profound initial neurologic manifestations [Both National Institutes of Health Stroke Scale (NIHSS) score and Barthel index]. In MR angiography, patients with CSCI showed more frequent single middle cerebral artery (MCA) stenosis, whereas NCSCI patients had findings that were more heterogeneous. In conclusion, we found that not all the patients with striatocapsular infarction had cortical dysfunctions. It is possible for lesions with similar size and location to have different manifestations (cortical or non‐cortical) according to their vascular integrity.
