Infarction of the corpus callosum is relatively rare in clinical practice, and the manifestations are mainly the following: 1. Patients may present with corpus callosum dissociation syndrome, which may manifest as loss of use, loss of writing, tactile naming inability, and manifestation of dissociative hand syndrome. 2. Frontal lobe type gait disorder may appear, and patients may manifest as wide basal, small gait walking without upper limb swing, and this symptom is a syndrome of hemispheric connectivity of the brain. If the damage is in the anterior 1/3 of the corpus callosum, it will cause loss of writing, left hand inflexibility, speech disorders, and possibly personality changes such as emotional indifference, forgetfulness, and inattention. In the middle 1/3 of the disease, the patient may experience hemiplegia, paraplegia, unilateral lower limb paralysis, urinary retention or loss of urine. In the posterior 1/3 of the fibrous link, damage to the audiovisual area on both sides can lead to hemianopia.
