Background: Anterior clinoidal meningiomas are heterogeneous types of lesions that comprise the
parasellar lesions group. Due to their close relationship with the optic nerve and internal carotid artery, they
become challenging pathologies for neurosurgeons.
Case Description: Female 47, presented with superior temporal quadrantanopsia on the right side. Magnetic
resonance image revealed type III clinoidal meningioma on the right side. She has undergone a pterional
craniotomy for an optic canal unroofing and tumor extraction. Two years of postoperative follow-up the
patient underwent a campimetry, which revealed an almost complete visual improvement.
Conclusion: To date, the best surgical technique has not yet been defined, so the choice of treatment and
surgical technique is based on each case and on the surgeons’ experience.
