Unknown Brain Case 3
40 y/o patient with a history of multiple sclerosis presenting with vision loss in the left eye.
The T1-weighted images, particulary with fat suppression, show enhancement around the left optic nerve at the apex of the orbit.
The T2-weighted images (not shown) were performed without fat suppression and were normal.
- Perioptic meningioma
- Optic nerve glioma
- Other inflamatory lesions of the optic nerve
Optic neuritis is fairly common in patients with multiple sclerosis. The lesions are typically bright on T2-weighted sequences and on enhanced T1-weighted images, though without fat suppression, many will be missed.
