Vitamin B(12), or cobalamin, deficiency is often unrecognized because the clinical manifestations are subtle; they are also potentially serious. We report a case of pseudothrombotic microangiopathy related to cobalamin deficiency. Vitamin B(12) deficiency, which is more commonly recognized in the context of malnutrition, should be considered in the context of microangiopathy.
维生素B12（钴胺素）缺乏常常未被识别，因为其临床表现不明显；但这些表现也可能很严重。我们报告一例与钴胺素缺乏相关的假性血栓性微血管病病例。在微血管病的情况下应考虑维生素B12缺乏，这种缺乏在营养不良背景下更常被认识到。
