Optic Nerve Neuritis (MR).

T2 image shows enlargement of the right optic nerve if compared to the left one.

Flair image shows tiny altered foci in left peri ventricular region.

MR angiography revealed non visualization of the right vertebral artery.

MR venography (normal).

PROTOCOL:

T1W – Sagittal & axial scans
T2W – Axial & coronal scans
FLAIR – Axial scans 

FINDINGS:

-Revealed:
• Enlarged right optic nerve (6.2 mm) if compared to the left one (3.4 mm) at the retro bulbar region.
• Tortuous right optic nerve.
• Tiny peri ventricular altered signal foci.
• No abnormal enhancement in both optic nerves.
• No abnormal enhancement in the brain.
• Non visualization of the right vertebral artery.
• Normal morphology of the rest of the cerebral MR angiography.
• Normal morphology of the MR venography.


-Brain parenchyma shows normal grey white matter differentiation and signal intensities.  No focal mass lesion is seen.
-Lateral and third ventricles are normal in size and position. Septum is in midline.  There is no midline shift.
-Basal cisterns, cortical sulci and gyri are normal in appearance.
-Corpus callosum shows normal MR morphology.
-Brain stem and cerebellum show normal signal intensities.  
-Fourth ventricle is normal in size and is midline in position.


OPINION:

• Picture is suggestive of right optic nerve neuritis for clinical correlation.
• Tiny peri ventricular foci of altered signal for follow up after 3 months if clinically indicated.
• Non visualization of the right vertebral artery.
