Bilateral Optic Nerve Sheath Meningioma with Intracanalicular and Intracranial Component in a 25-year-old Saudi Patient.

Badr MA, Elkhamary SM, Al Sabbagh S, Al Turjoman A - Middle East Afr J Ophthalmol (2008)

Bottom Line: A meningioma is a benign neoplastic lesion from meningothelial cells of the meninges.They usually involve the intracanalicular portion of the optic nerve but may extend into the optic canal and through it to occupy the intracranial space.The diagnosis was delayed more than six years from initial symptoms.

ABSTRACT
Bilateral optic nerve sheath meningioma is rare. A meningioma is a benign neoplastic lesion from meningothelial cells of the meninges. They usually involve the intracanalicular portion of the optic nerve but may extend into the optic canal and through it to occupy the intracranial space. We present a case of 25-year-old Saudi female with bilateral optic nerve sheath meningioma. The diagnosis was delayed more than six years from initial symptoms.

Post contrast T1-weighted MR image axial MRI with fat saturation showed Tubular growth pattern of bilateral optic nerve sheath meningioma as diffuse enhancement along the length of the left Intraconal optic nerve sheath (black arrows). Optic nerve is seen as central linear hypointensity in comparison to enhanced meningioma on either side, producing the tramtrack sign (A). Axial and coronal T1-weighted, contrast-enhanced images (B and C) showed diffuse enlargement and enhancement along the RT intracanalicular (white arrows) optic nerve sheath with en-plaque growth along the walls of the sulcus chiasmaticus, giving a “rose thorn” appearance (black long arrow). Contrast-enhanced coronal and sagittal T1-weighted MR image, with fat suppression through the optic nerve in the midorbit, illustrates enhancing mass affecting the RT planumsphenoidale and inferior orbital fissures with en-plaque growth of tumor within the right optic nerve sheath. The left side meningioma, the tumor was limited to the canal and the immediately adjacent walls of the sulcus chiasmaticus and orbital apex (D and E).

Mentions: Post contrast T1-weighted MR image axial MRI with fat saturation (Fig 2 A–D) showed tubular growth pattern of bilateral optic nerve sheath meningioma as diffuse enhancement along the length of the left intraconal optic nerve sheath (black arrows). Optic nerve is seen as central linear hypointensity in comparison to enhanced meningioma on either side, producing the tram-track sign with extensive enhancement along the RT intracanalicular optic nerve sheath (white arrows) with en-plaque growth along the walls of the sulcus chiasmaticus, giving a “rose thorn” appearance(black long arrow). Contrast-enhanced coronal and sagittal T1-weighted MR image, with fat suppression through the optic nerve in the midorbit (Fig 2 D–E), illustrates enhancing mass affecting the RT planumsphenoidale and inferior orbital fissures with en-plaque growth of tumor within the right optic nerve sheath.
