Left and right orbits MRI scans with presence of small nodules on both optic disks, especially on the right eye, which was compatible with bilateral leukemic infiltration. Optic nerves, chiasma, and other neurological segments were unaffected. (A): T2-weighted, a small nodule is best evidenced on the left eye; (B): T1-weighted without contrast and fat suppression, evidencing no impairment of optic nerves; C/D: T2-weighted with gadolinium contrast, small nodules of the left eye are highlighted by the gadolinium contrast
