The most common symptom of pontine infarction is crossed paralysis, which manifests as facial paralysis and tongue paralysis on the affected side of the face, as well as central paralysis of the contralateral limbs or attempted limb movement, usually due to infarction of the lower part of the pontine infarction on one side of the brain. If bilateral pontine infarction occurs at the same time, tetraplegia will be manifested, as well as dysphagia, high fever, and impaired consciousness. Depending on the blood vessels involved, the general symptoms are different. Patients with pontine infarction may also experience dizziness, spinning of vision, nausea, vomiting, and other symptoms. The most common cause of pontine infarction is the branching of the basilar artery, the formation of atherosclerotic plaque, resulting in narrowing of the lumen, and when blood flow slows down thrombus formation, resulting in occlusion of the blood vessel, which can cause acute pontine infarction.
