Summary Two women aged 48 and 73 years, respectively, presented with unilateral visual disturbance. On admission, magnetic resonance imaging (MRI) showed an extraaxial mass in the parasellar region. Contrast-enhanced fast imaging with steady-state acquisition (CE-FIESTA) showed that the optic nerves were compressed and encased by the tumors. At an early stage of surgery, we performed decompression of the optic nerves to avoid optic nerve injury. Both the patients were relieved of visual disturbances without any postoperative neurological deficit. In conclusion, CE-FIESTA is a useful diagnostic tool for preoperative evaluation of the optic nerves in patients with skull base meningiomas. Decompression of the optic nerves should be performed at an early stage of surgery in meningioma patients presenting with visual disturbance.
