In recent years, knowledge about the physiological functions of the Nogo-A protein has grown considerably, and this molecule has evolved from being one of the most important axonal regrowth inhibitors present in central nervous system (CNS) myelin, to several other potentially important roles in different areas such as nervous system development, epilepsy, vascular physiology, muscle pathology and CNS tumors. Therapeutically, targeting the Nogo-A protein by means of the immune response has been tried in an attempt to block neurite growth inhibition and promote regeneration in spinal cord injury models; the immune response to Nogo-A, however, has not been extensively studied. We propose to review recent evidence that Nogo-A may also play an important role in autoimmune demyelinating diseases such as experimental autoimmune encephalomyelitis and multiple sclerosis, including that Nogo-66 derived epitopes are encephalitogenic antigens in susceptible mouse strains, and that the immune response to Nogo-66 antigens includes both strong T cell and B cell activation, with epitope spreading of the antibody response to other myelin molecules. In CNS immunotherapy, careful targeting of neural self-antigens is a prerequisite in order to avoid unexpected deleterious effects, and increasing knowledge about the immune response to Nogo-A may provide a safe basis for the development of relevant therapeutic alternatives for several neurological conditions.

A malignant neoplasm in the central nervous system with diffuse white matter changes on magnetic resonance imaging (MRI) is rare in children. It could be misdiagnosed as acute disseminated encephalomyelitis. This report presents our experience based on 4 patients (3 male, 1 female; aged 7-13 years) whose MRI showed diffuse lesions in white matter and who were initially diagnosed with acute disseminated encephalomyelitis. All of the patients received corticosteroid therapy. After brain biopsy, the patients were diagnosed with gliomatosis cerebri, primitive neuroectodermal tumor and central nervous system lymphoma. We also provide literature reviews and discuss the differentiation of central nervous system neoplasm from acute disseminated encephalomyelitis.

Major advances have been made in the clinical and radiologic characterization of children presenting with the different forms of an acquired inflammatory demyelinating syndrome (ADS) such as acute disseminating encephalomyelitis, neuromyelitis optica spectrum disorders, and clinically isolated syndromes. Nevertheless, a proportion of cases that present with similar symptoms are due to a broad spectrum of other inflammatory disorders affecting the white matter, primary CNS tumors, or neurometabolic diseases. The clinician therefore has to be aware of the different forms of ADS, the risk factors for a chronic-relapsing course, and features that indicate an alternative diagnosis. The goal of this article is therefore to provide an outline of a pathway for evaluating pediatric patients with a presumed inflammatory demyelinating disorder and discussing the spectrum of the more common differential diagnoses.
