1. Medial medullary syndrome: results from Vertebral artery occlusion. As a result, the patient will demonstrate contralateral paralysis of the arm and leg, contralateral loss of tactile, vibratory, and position sense, and tongue deviation to the injured side.
2. Lateral midpontine syndrome: results from lesion of the lateral pons can cause the, which results in impaired sensory and motor function of CN V (the trigeminal nerve) with accompanying limb ataxia.
3. Medial midpontine syndrome: an ischemic lesion of the medial pons. Common characteristics include ipsilateral limb ataxia and contralateral eye deviation and paralysis of the face, arm, and leg. Impairment of touch and position sense is variable.
4. Wallenberg syndrome: occlusion of posterior inferior cerebellar artery → lesion of the lateral medulla, presenting as an ipsilateral Horner syndrome; loss of pain and temperature sensation of the face; weakness of the palate, pharynx, and vocal cords; and cerebellar ataxia. Loss of pain and temperature sensation on the contralateral side of the body.
