Metabolic and toxic myelopathies usually occurs due to several different causes. Metabolic myelopathy usually occurs due to deficiency of a nutrient, such as vitamin B12. Toxic myelopathy occurs secondary to the exposure to an external toxic agent. Although they may have a difficult diagnosis, determination of the specific cause of myelopathy is of utmost importance, because many causes are amenable to treatment. Although they have many clinical, electrophysiologic, and neuropathologic similarities, imaging may aid in the suspicion of toxic or metabolic myelopathy. The aim of this article, is to review the imaging features of the main toxic and metabolic myelopathies.
代谢性和中毒性脊髓病通常由多种不同的原因引起。代谢性脊髓病通常是由于营养物质（如维生素 B12）缺乏引起的。中毒性脊髓病继发于接触外部毒物。虽然它们可能难以诊断，但确定脊髓病的具体病因至关重要，因为许多病因是可以治疗的。尽管它们在临床、电生理和神经病理学方面有许多相似之处，但影像学检查可能有助于怀疑中毒性或代谢性脊髓病。本文的目的是回顾主要的中毒性和代谢性脊髓病的影像学特征。
