Selective proprioceptive loss from a thalamic lacunar stroke.
In an elderly woman a small thalamic infarct, documented by computed tomography and nuclear magnetic resonance imaging, caused proprioceptive loss contralaterally without impairment of other sensory modalities. This patient, the first so reported, demonstrates the anatomic separation of spinothalamic and dorsal column/medial lemniscus sensory modalities in the human thalamus.
