Optic neuritis (ON) is an inflammatory condition of the optic nerve that is commonly seen in central nervous system demyelinating diseases such as multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and myelin oligodendrocyte glycoprotein antibody (MOG-IgG)-related diseases.

Targeted imaging of the orbits (including fat-saturated T1 C+ and T2 weighted sequences (see MRI protocol: orbit) may demonstrate typical features of optic neuritis: optic nerves appearing hyperintense.

Distinguishing between NMO and MS is important in guiding differing treatments, but biomarkers of NMO and MS can be absent early in the disease. The classic presentation of NMO is with the triad of optic neuritis , longitudinally extensive myelitis, and positive anti-AQP4 antibody, although a far wider.

MOGAD often present with recurrent optic neuritis (ON), and it can also develop as a compartment of neuromyelitis optica spectrum disorder (NMOSD).

Magnetic resonance imaging (MRI) demonstrated several hyperintense white matter lesions in the brain of 15/20 patients with acute optic neuritis. Oct 1, 2008 · Imaging provides crucial information regarding emergent orbital abnormalities, and the radiologist fulfills an important role in guiding patient care and contributing to favorable outcomes.

Oct 1, 2015 · Because the macular region was unremarkable, a diagnosis of optic neuritis was suspected and a referral to a neurologist, or neuro-ophthalmologist, is necessary since optic neuritis can be associated with demyelination and MS.

. Knowledge of the imaging features of nontraumatic orbital conditions commonly seen in the emergent setting—infections, inflammation, vascular abnormalities, and retinal and choroidal detachments—is.

PURPOSE: To examine the benefits of combined fat- and water-suppressed T2-weighted magnetic resonance (MR) images in the diagnosis of optic neuritis.

The MRI sequences demonstrate a left unilateral swelling of the retrobulbar intra-orbital segment of the optic nerve extending to the intracranial segment, of high T2 signal with.

MRI may also identify any white matter lesions suggestive of MS (Figure 1).

However, it is usually reserved for demyelinating events, isolated or with multiple sclerosis (MS) or acute disseminated encephalomyelitis (ADEM) or neuromyelitis optica (NMO).
