  • Title: Herniated gyrus rectus causing idiopathic compression of the optic chiasm.
    Author: Smith J, Jack MM, Peterson JC, Chamoun RB.
    Journal: Clin Neurol Neurosurg; 2017 Feb; 153():79-81. PubMed ID: 28068526.
    Abstract:
    Anomalies in the frontal lobe can interfere with visual function by compression of the optic chiasm and nerve. The gyrus rectus is located at the anterior cranial fossa floor superior to the intracranial optic nerves and chiasm. Compression of these structures by the gyrus rectus is often caused by neoplastic or dysplastic growth in the area. We report a rare case of a herniated gyrus rectus impinged on the optic chiasm and nerve without a clear pathological cause for the herniation.
