Visual field test at presentation. A remarkable upper temporal visual field defect and slight defect were observed in the right and left eye, respectively.

In a visual field test by Goldmann perimetry, a remarkable upper temporal visual field defect and slight defect were observed in the right and left eye, respectively [Figure 1].
Magnetic resonance (MR) imaging at presentation. On sagittal of T2-weighted image (a) and coronal sections of (b) T1- and (c) T2-weighted images, herniation of the gyrus rectus (*) and right optic nerves (white arrow head) is shown. The sagittal section of contrasted fat-saturated T1-weighted MR image (d) shows an enhancement at the diaphragm (black arrow head).

Magnetic resonance (MR) imaging showed herniation of her right optic nerve and gyrus rectus into the sella turcica, which was considered to have resulted in the visual disturbance [Figure 2].
Visual field test at presentation at 1 month post presentation. Defect of visual fields was well improved although an only slight visual defect was left in the right eye.

Corrected visual acuity was 20/25 in the right eye and 20/20 in the left, while only a slight visual defect was left in the right eye [Figure 3].
Coronal sections of the repeated T1-weighted magnetic resonance images at 1 month post presentation. The herniation of the right optic nerve (arrow head) and gyrus rectus (*) improved.

MR imaging at the time (1 month post presentation) showed the disappearance of the optic nerve and rectal gyrus herniation due to the expansion of the intrasellar cyst [Figure 4].
Coronal sections of repeated (a) T1- and (b) T2-weighted magnetic resonance images at 3 months post presentation. The bilateral optic nerves were cranially dislocated, resulting in remarkable expansion of the intrasellar cyst (arrow head). The contents of the cyst had a signal similar to signals of cerebrospinal fluid.

MR imaging at 3 months postpresentation showed that the bilateral optic nerves were cranially dislocated [Figure 5], while the visual disturbance was almost absent with a very narrow and slight temporal defect of the visual field in her right eye.
