Background
Hand knob infarction induced focal weakness of contralateral hand or distal arm, only accounts for less than 1% of all ischemic strokes. To date, there is no case with pain during sleep as the onset symptoms being reported. The atypical symptoms of hand knob infarction might increase the risk of delaying treatment especially in the hyperacute phase of stroke.
Case presentation
A 70-year-old man awoke from sleep due to sudden pain of his right medial wrist and presented to the emergency department with difficulty extending his right index and middle fingers within the time window of intravenous thrombolysis. But the intravenous thrombolysis was not given based on the NIHSS score (0) and atypical symptoms. MRI showed multiple DWI hyperintense lesions, including partial left hand knob area and left posterior central gyrus. CTA showed a severe focal stenosis of proximal left internal carotid artery.
Conclusions
The hand knob infarction might onset with unusual pain and should be carefully inspected in patients combined with acute onset of focal hand paresis.
