ABSTRACT

Diagnosis: Optic nerve sheath meningioma.

History: 70 year old female for follow up follow up tumor.

Findings: Film #1: Nonenhanced axial CT image of the head shows a bilobed circumscribed hyperdense lesion centered on the left optic nerve that extends to the orbital apex. No evidence of extension is seen outside the bony orbit. Film #2 and 3: Axial T1 and T2 weighted images, respectively, shows a bilobed T1 hypointense and T2 heterogenously hyperintense mass arising from the left optic nerve sheath with mildly associated proptosis. There is a clear demarcation present between the mass and optic nerve. Film #4: Axial T1 postgadolinium with fat saturation shows the mass to enhance intensely and is only slightly inhomogeneous.

Ddx: 1. Optic nerve sheath meningioma. 2. Neurofibroma. 3. Cavernous hemangioma. 4. Intraconal hematoma.

Dxhow: MR

Exam: Not available.
