A small cortical infarction confined to the medial location of the precentral knob on the precentral gyrus may cause isolated shoulder palsy. However, there are no reports indicating intracerebral hemorrhage as a cause of isolated shoulder palsy. We herein report the case of a 48-year-old man who presented with isolated shoulder palsy as an initial symptom of subcortical hemorrhage at the precentral gyrus. Such cases may be easily misdiagnosed as shoulder or cervical spine problems. The distribution of muscle weakness is the key to an accurate diagnosis.
