When hand weakness is linked to a brain lesion, there is risk of misdiagnosis. A case of hand weakness related to stroke is presented. The electromyography report indicated a segmental lesion of the median nerve at the wrist. Thus, the patient was initially diagnosed with carpal tunnel syndrome, and was referred to the orthopedic department for release surgery. Because the symptom was immediate and did not include hand numbness, the orthopedic surgeon ruled out the previous diagnosis and ordered a head CT scan, which revealed stroke. Aspirin and other medications were given. Percutaneous carotid balloon angioplasty with stent implantation and percutaneous vertebral artery balloon angioplasty were performed. The weakness of the left hand was greatly improved. So far, only a few cases suggest that hand weakness may be linked to stroke. Therefore, physicians should pay attention to physical examination.
