We report a case of bilateral useless hand syndrome, a rare presenting manifestation of vitamin B12 deficiency. A 38-year-old man, a strict vegetarian and a teacher by occupation, presented with acute onset clumsiness of both hands while performing fine movements. Detailed history-taking, examination of the patient and relevant investigations (complete blood count, serum vitamin B12 and MRI of the cervical spinal cord) were carried out. Laboratory analysis was suggestive of vitamin B12 deficiency and MRI demonstrated a lesion involving the posterior columns of the cervical cord. The patient was diagnosed as a case of non-compressive cervical myelopathy predominantly involving the posterior column due to vitamin B12 deficiency. Acute bilateral useless hand syndrome can be a rare presenting feature of vitamin B12 deficiency.
我们报告一例双侧无功能手综合征，这是维生素B12缺乏症一种罕见的表现形式。一名38岁男性，职业为教师，是严格素食者，在进行精细动作时双手突然出现笨拙。进行了详细的病史采集、患者检查及相关检查（全血细胞计数、血清维生素B12和颈髓MRI）。实验室分析提示维生素B12缺乏，MRI显示颈髓后柱有病变。该患者被诊断为因维生素B12缺乏导致的以颈髓后柱为主的非压迫性颈髓病。急性双侧无功能手综合征可能是维生素B12缺乏症一种罕见的表现特征。
