A case of anti-aquaporin-4 and anti-glutamate receptor antibodies positive myelitis presented with modest clinical signs.
We present a case of anti-aquaporin-4 antibody-positive myelitis, which suggests the high-risk syndrome of neuromyelitis optica, whose modest clinical signs were in conspicuous contrast to the extensive spinal cord lesions demonstrated on magnetic resonance (MR) imaging. Follow-up MR imaging showed marked improvement of lesions. Interestingly, an anti-glutamate receptor antibody, which has been suggested to cause dysfunction of N-methy-D-aspartate receptor on neuron, was detected in the cerebrospinal fluid of the patient. We discuss the case and related literature.
