Pure sensory stroke is usually caused by a posterolateral thalamic lacune [1]. It has also been described in association with small intracerebral hemorrhages [2, 3], including a few located in the brainstem [4–12]. The sensory loss may involve the entire or a part of the hemibody, or have a cheiro-oral distribution [5, 7, 9, 10], being limited to the hand and the mouth or the perioral area of the same side. This particular distribution is related to damage to a restricted sector of fibers of the trigeminothalamic tract.
