The term Neuromyelitis optica spectrum disorder (NMOSD) is a recently proposed for neuromyelitis optica and related syndromes. Along with serum anti-aquaporin 4 antibody status, detection of a lesions extending over ≥3 contiguous spinal cord segments (longitudinally extensive transverse myelitis, LETM) associated with acute myelitis is the most specific neuroimaging characteristic of NMOSD. 1 We present a case of NMOSD with delayed lesion on spinal cord magnetic resonance imaging.

Extensive Transverse Myelitis

The cardinal features of neuromyelitis optica spectrum disorder (NMOSD) are optic neuritis, longitudinal extensive transverse myelitis and area postrema syndrome. Olfactory dysfunction is not listed as a feature in the NMOSD diagnostic criteria. Here, we present an aquaporin-4 antibody positive patient who, in addition to classical features of NMOSD, developed acute anosmia with magnetic resonance imaging (MRI) evidence of olfactory bulb abnormalities. While the association of anosmia and NMOSD has been rarely noted previously, to our knowledge, no prior cases have found this to be one of the presenting features of a relapse nor have they identified acute radiological correlates.

Extensive Transverse Myelitis

We studied cranial magnetic resonance imaging (MRI) lesions in three women with acute attacks of recurrent longitudinally extensive transverse myelitis (r-LETM), recurrent-optic neuritis (r-ON) and r-LETM-CNS. Neuromyelitis Optica -immunoglobulin (IgG) antibody was positive in all cases. Brain MRI (1.5 Tesla) was performed according to protocol from consortium MS centre. We described the cranial lesions in brain MRI of acute relapses. These lesions were different from MS, most had an asymptomatic course which disappeared with time, protocol from consortium of MS centre criteria for brain MRI and seropositivity of NMO-IgG are useful tools for differentiate acute lesions of NMO/MS.
