A rare case of acute choreoathetosis after acute stroke is presented. This 66-years-old, right-handed Caucasian woman presented with weakness of her right arm and right leg with dysarthria, which resolved by the time she arrived in the emergency department. No obvious focal sign apart from the abnormal choreoathetoid movement of the right arm and leg and of the neck was present. Her medical history included atrial fibrillation without anticoagulation. CT head was nil acute (Alberta Stroke Program Early CT Score of 10). CT angiography of the carotids showed a hyperdense M2 segment of the left middle cerebral artery. Intravenous thrombolysis immediately followed by thrombectomy was decided. Using the Penumbra aspiration device (ACE 68) two clots were removed with two aspirations. A small distal clot remained but partial recanalisation (Thrombolysis in Myocardial Infarction/Thrombolysis in Cerebral Infarction 2b) was achieved. 30 seconds after restoring blood flow, the choreoathetoid movements ceased. The patient was brought to intensive care for further monitoring, which was uneventful.
