Although the somatosensory afferent of the tip of the tongue runs proximal and parallel along the spinothalamocortical and trigeminothalamocortical pathway up to the sensory cortex, central involvement has been rarely described in cases of nongustatory sensory disturbance at the tip of the tongue. In a hypertensive woman who experienced an acute onset of an isolated numbness at the tip of her tongue, recent small infarctions were found at the postcentral gyrus of the right parietal lobe. Thus, central involvement should not be neglected in the case of sensory disturbance at the tip of tongue.
