ABSTRACT

Diagnosis: Optic nerve meningioma - intraconal

History: This 50 year old woman had double vision in all gaze directions and decreased visual acuity in the left eye.

Findings: Fig 1. Fat suppresed T1 axial MRI showing the retro-ocular, intraconal mass. Fig 2. Gross resection specimen showing the mass surrounding the optic nerve. Fig 3. Histological section showing whorls of neoplastic cells abutting on the surface of the optic nerve. Fig 4. Higher magnification showing the indistinct cytoplasmic margins, vesicular nuclei and occasional intranuclear vacuoles.

Ddx: Differential Dx for Intraconal Mass: <li>Optic nerve glioma (fusiform enlarged optic nerve w/enhancement) <li>Optic nerve meningioma (surrounds a normal nerve) <li>Optic nerve metastases <li>Granulomatous disease <li>Schwannoma and Neurofibroma (NOT intrinsic to ON - but may be adjacent)

No MeSH data available.


Higher magnification showing the indistinct cytoplasmic margins, vesicular nuclei and occasional intranuclear vacuoles consisent with a meningothelial meningioma. Virtually no psammoma bodies were present in the lesion.
