The cortical motor hand area is a knob-like structure of the precentral gyrus, with an inverted omega or horizontal epsilon shape. Isolated hand weakness is infrequently observed and is usually due to small cortical infarcts of this hand knob structure. Isolated hand palsy is sometimes restricted to radial-sided fingers or ulnar sided-fingers. Uniform weakness in all fingers may also occur. We present 2 patients with small cortical infarcts of the cortical hand knob due to different etiologies. A 61-year-old male had right hand weakness restricted to his first and second digits. He had a small cortical infarct on the hand knob area due to emboli from ulcerative plaque of the ipsilateral internal carotid artery. The other patient, a 23-year-old female with sickle cell anemia, had uniform left hand weakness due to an epsilon-shaped infarct on the right precentral gyrus. An obstruction of the small cerebral artery supply to the hand knob area due to sickle cell anemia was the likely pathogenic mechanism. It is suggested that isolated hand weakness due to small cortical infarcts may have different etiologies, most commonly homodynamic or embolic processes. Conditions that rarely cause brain infarction, such as sickle cell anemia, deserve clinical attention. Investigations of strokes must include anemia tests. Patients with predominant weakness of the radial group of fingers due to cortical infarct must be checked for embolism.

Keywords: Stroke, hand, sickle cell anemia.
