Clinical and imaging analysis of corpus callosum infarction

Objective To investigate the clinical and imaging characteristics in patients with corpus callosum infarction.Methods The clinical data of 416 patients meetingthe diagnosis of cerebral infarction Were collected,in which,8 patients Were confirmed as corpus callosum infarction by MRI.Results Corpus callosum infarction accounted for 1.9% of all patients with cerebral infarction.CT scan did not show the corpus callosum infaretiom in 7 patients.The nonenhanced MRI revealed the lesions.The enhanced MRI revealed the lesion in another patient.The infarction foci were not only involved in the corpus callosum(knee,body or splenium),but also cornplicated with frontal lobe,occipital lobe and thalamus infractions.The clinical manifesta tions of the corpus callosum infarction were different due to the specific lesion sites.The simple infarction in the body of the corpus callosum mainly presented as contralateral paraparesis.atria,and left limb apra.xia;the infarction in the knee of the corpus callosum mainly presented as lower limb paralysis or contralateral paraparesis;the infarction in the splenium of the corpus callosum presented as limb paralysis and dizziness;the lacunar infarct in the corpus callosum had no obvious clinical manifestations.The patients who complicated with frontal lobe and thalamus infarction had behavioral and psychological syrnptonm,including mental retardation,language abnormalities.and incontinence.Conelusions Corpus callosum infarction is not common.MRI is the basis of diagaosis.The clinical manifestation is lack of specificity.and it is agsociated with the location of corpus callosum infarction and whether it comolicates with the infarction on other part.
