False-positive cases (E-K): sagittal FLAIR image showing Dawson-finger T2-hyperintense lesions perpendicular to the ventricle, typical of multiple sclerosis (E) axial postgadolinium T1-weighted images showing multiple areas of nodular enhancement in the pons that brainstem biopsy confirmed to be a histiocytic disorder (F) axial T2-weighted image showing a peripheral dorsolateral hyperintense lesion abutting the surface of the spinal cord, in another patient with multiple sclerosis (G) sagittal T2-weighted image showing a faint longitudinally extensive T2-hyperintense lesion accompanied by marked cervical spinal cord swelling with an intralesional cyst (H), also appreciable on axial images (I), which biopsy confirmed to be a glioma sagittal (J) and axial (K) T2-weighted spinal cord MRI showing normal signal intensity and initial atrophy in a young adult man with X-linked adrenomyeloneuropathy.

Any medication started would be discussed in full detail if needed.True-positive cases (A-D): axial fluid-attenuated inversion recovery (FLAIR) image showing large, multifocal, poorly demarcated lesions on brain MRI in a patient with an acute disseminated encephalomyelitis attack in MOG-IgG1–associated disorder (MOGAD) (A) axial postgadolinium T1-weighted orbit MRI showing longitudinally extensive enhancement of the left optic nerve sheath in a patient with optic neuritis as a manifestation of MOGAD (B) sagittal T2-weighted images showing a longitudinally extensive myelitis lesion along the lower thoracic spinal cord, with predominant involvement of the central gray-matter on axial images in MOGAD (C and D). These types of medicine are used to control your child’s immune system and to damp down inflammation. Medicines that may be used include azathioprine, mycophenolate mofetil or in some cases rituximab. If a child continues to have relapses, then maintenance treatment may be required to prevent further relapses. Both these treatments will be explained in full detail if needed.įor many children, after an initial attack, it can be difficult to predict if further attacks will happen so it is not always beneficial to start a long term treatment. In rare cases, if high dose steroids do not improve your child’s symptoms, other treatment may need to be considered, such as intravenous immunoglobulins (IVIGs) or plasma exchange. Steroids do not change your child’s risk of a relapse. Steroids have both short and long term side effects so your child will not usually stay on them for a long time. These side effects will be discussed with you in more detail at the time.

Your child may then start an oral course of steroid tablets and you will be given a plan of how to reduce these gradually.Ĭhildren usually respond very well to steroid treatment during this acute phase. This will usually be given at high dose for three to five days via a cannula into a vein. Intravenous steroid treatment is often used to treat the acute symptoms of demyelination to try to reduce the inflammation that has occurred. How is MOG antibody demyelination diagnosed? These relapses could happen either months or even years apart and therefore it can be difficult to predict.
Transverse myelitis is inflammation of the spinal cord. Optic neuritis is demyelination of the optic nerve and can affect one or both eyes. Some children may initially present with acute disseminated encephalomyelitis (ADEM) which is an inflammatory condition that mainly affects the brain and others may have signs of optic neuritis or transverse myelitis. Symptoms of MOG antibody demyelination can be variable from person to person and can range from mild to severe depending on which parts of the brain are affected.
