Abstract Intracranial meningiomas mostly affect patients in their fifth decade and beyond, raising pertinent questions regarding the risk of surgery, particularly in the elderly. Here, we describe the case of a septuagenarian patient with occipital meningioma causing severe visual field cuts that experienced full recovery of the visual function after a Simpson I resection of the lesion. This case illustrates the potential of recovery of the brain, even in the case of severely impaired function in elderly patients. To complete the picture, we review the literature on occipital meningiomas, advocating for systematic reports and increase data collection on postoperative neurological recovery in the elderly. Keywords Occipital meningioma . Visual field restoration . Brain plasticity
Introduction Intracranial meningiomas (ICMs) are benign lesions representing 25–40% of all operated primary intracranial tumors [14]. In general, symptomatic patients or in the presence of documented tumor growth on serial magnetic resonance imaging (MRI), maximal safe surgical resection is recommended [8]. ICMs are diagnosed in septuagenarians

and octogenarians [13]. Although they are often cured by surgery [10], ICMs are rarely life-threatening. This raises pertinent questions regarding the risk of surgery and the potential benefits of surgery, particularly in the elderly [4, 12, 13, 23]. With respect to risks, technical and medical innovations in microsurgery and anesthesiology have had a tremendous impact on the surgical management of brain tumors [21], up to a point where cranial surgery is considered even in patients at advanced ages [12, 13]. However, the risk of meningioma surgery is not negligible [5, 11, 13]. Little is known about the potential of neurological recovery after surgery in the elderly, in the presence of a preoperative neurological deficit. Therefore, some surgeons might be reluctant to proceed with surgery in an older patient, even th
