We also found that patients with MOG-Ab disease more commonly presented with multiple spinal cord lesions than patients with AQP4-Ab disease did, which agrees with results presented in a 2019 study by Dubey et al.14 Short cord lesions may be misdiagnosed as MS, particularly in pediatric populations, in which patients with MOG-Ab disease have received an MS misdiagnosis in the past.15 Therefore, axial imaging of the spinal cord is crucial in these cases, as is brain imaging. Here, AQP4 is linked to myeloid sarcoma.
