The optic chiasm, optic tracts, and optic-nerve sheath complexes appeared normal. Diffuse heterogeneous thickening of the calvarium was present. A coronal T2-weighted image of the head and optic ...

(Left) T1-weighted with gadolinium sagittal MRI; (Right) T1-weighted with gadolinium coronal MRI. Note the large enhancing mass in the region of the sella that is growing up into and displacing the ...

Sagittal and coronal MRI scans provide reliable information concerning the relationship of the mass to the optic nerve and chiasm, as well as the hypothalamus. Coronal MRI may demonstrate lateral ...

Coronal and axial contrast-enhanced T1-weighted ... The optic nerve fibers extend 50 mm caudally from the retina to the optic chiasm. A lesion anywhere along the optic nerve can cause monocular ...

1 The differential diagnosis for a junctional lesion (i.e., a lesion occurring at the junction of the optic chiasm and optic nerve) includes neoplasms such as pituitary adenoma, meningioma, ...

Normally, the left half of your brain receives visual information from the right side of both eyes, and vice versa. Some information from your optic nerves crosses to the other half of the brain ...

[1] Patients presenting with lesions abutting the optic chiasm should be referred for a complete neuro-ophthalmological evaluation with funduscopic examination, visual acuity and precise plotting ...
