Neuroepithelial cyst causing homonymous hemianopia treated through surgical marsupialization under visual-evoked potentials: A case report

NECs should be carefully assessed to rule out symptoms associated with mass effects. This case and others reported in the international literature show that occipital neuroepithelial cysts can benefit from surgical treatment with meticulous preoperative planning. The aid of neuromonitoring is crucial to identify anatomical variations and cortical functionality that are potentially distorted in the presence of these lesions.
