Abstract
The aim of this study is to present a diagnostic and therapeutic approach in patients with LETM. In a period between June 2008 and June 2010, all patients who fulfilled criteria for LETM were included in the study. All patients underwent a standardized protocol of investigations presented in this paper. Ten patients were included (5 male, 5 female, with the age distribution from 24 to 70 years). Four patients were diagnosed with NMO/spatially limited NMO spectrum disorder, three patients were diagnosed with spinal cord ADEM, two multiple sclerosis (MS) and one patient with copper deficiency myelopathy. Laboratory support for the diagnosis of NMO was positive NMO-IgG antibody; for the diagnosis of ADEM signs of peripheral nervous system involvement on electromyoneurography; and for the diagnosis of MS brain MRI lesions typical for MS, as well as positive oligoclonal bands (OCB) in the cerebrospinal fluid (CSF). All cases with inflammatory myelopathy were treated either with steroids or plasma exchange and copper replacement was started in the case of copper deficiency. The mean time from the first symptom until the final diagnosis was 16.3 months (range 1 month to 7 years). As each of idiopathic inflammatory demyelinating diseases that can present with LETM have specific therapy, the postponement in making the correct diagnosis can lead to a poor recovery. In patients with LETM, a standardized diagnostic approach can result in a correct diagnosis and appropriate treatment.
