Case Reports
[Anesthesia paresthetica: contribution of a new case and evolutive study using magnetic resonance].
Patients with subclinical cobalamin deficiency may develop a subacute myeloneuropathy after nitrous oxide anesthesia. Frequently they have hematologic manifestations, however there is only a few reports of spinal lesions shown on MR and particularly of the effects of cobalamin replacement therapy on these lesions. ⋯ We discuss the importance of preoperative hematologic manifestations for select high risk patients and prevent this complication. On the other hand, we consider MR as a useful tool to improve our knowledge in the pathophysiology of the neurologic manifestations of the process.
