ABSTRACT

Diagnosis: optic neuritis

History: 49 y.o. white man who had an acute onset of bilateral decreased visual acuity.

Findings: Multiple axial MR images demonstrate enlarged optic nerves bilaterally, with stranding of intraconal fat, with avid enhancement of the optic nerves and the surrounding intraconal fat bilaterally on the post-contrast T1-weighted images with fat-suppression, without fusiform enlargement of the nerves or tram-track-like enhancement seen in optic glioma or optic nerve meningioma, respectively. MR images of the brain (not shown) demonstrated no other abnormalities.

Ddx: optic neuritis, bilateral: - multiple sclerosis (initial presentation) - acute disseminated encephalomyelitis - orbital pseudotumor

Dxhow: abnormal enhancement and enlargement on MR

Exam: bilateral papilledema, left greater than right

No MeSH data available.
