ABSTRACT
BACKGROUND AND PURPOSE:
There are few clinico-radiological data on optic neuritis (ON) with myelin oligodendrocyte glycoprotein antibody (MOG-IgG). The objective was to characterize the clinico-radiological phenotype and outcome of patients with MOG-IgG-related ON.METHODS:
The records of all adult patients admitted in three medical centres with MOG-IgG-associated ON who underwent orbital and brain magnetic resonance imaging (MRI) at the acute phase were reviewed. Spinal cord MRI within 1 month from the ON and all of the follow-up MRI were reviewed.RESULTS:
Of 62 patients, 41.9% had bilateral ON and 66.2% optic disc swelling. On initial MRI, lesions were anterior (92%), extensive (63%) and associated with optic perineuritis (46.6%). Silent brain lesions were found in 51.8% of patients but were mainly non-specific (81%). Of 39 individuals with spinal MRI at onset, nine had abnormal findings (four were asymptomatic). Two symptomatic patients had longitudinally extensive myelitis with concurrent H-sign. At last follow-up, 5% of patients had visual acuity ≤0.1. Brain MRI remained unchanged in 41 patients (87%).CONCLUSIONS:
Our study supports a mostly benign ophthalmological course of MOG-IgG-associated ON, despite initially longitudinally extensive lesions and development of optic nerve atrophy on orbital MRI. Spinal MRI could be of interest in detecting silent suggestive lesions.Palabras clave
