Small cortical infarctions can produce isolated motor paresis in the upper extremities. Several cases of isolated hand or finger paresis have been reported, but isolated shoulder weakness is extremely rare. We report here a patient who developed isolated shoulder weakness due to a small cortical infarction in the medial precentral gyrus
