Meningiomas are among the most common primary intracranial tumors arising from the
meningothelial cells of the arachnoid layer. Though typically benign, their surgical manifestations
vary significantly depending on their size, location, vascular supply, and relationship with adjacent
neurovascular structures. Surgical management remains the mainstay of treatment, and
understanding the diverse presentations of meningiomas is critical for neurosurgeons.
Supratentorial meningiomas, such as those located at the convexity or parasagittal region, often
present with seizures or focal neurological deficits, and can be accessed relatively easily via
craniotomy. In contrast, skull base meningiomas—including sphenoidal wing, clinoid, and
petroclival types—pose greater surgical challenges due to their proximity to cranial nerves and
vital vasculature [1]. Spinal meningiomas, though less common, require a different surgical
approach and frequently result in symptoms of cord compression. Moreover, certain meningiomas
exhibit invasive behavior or recur after resection, necessitating complex surgical strategies,
including staged operations or combination with adjuvant therapies. Technological advancements,
such as neuronavigation, intraoperative imaging, and microsurgical techniques, have greatly
improved surgical outcomes. A tailored approach considering tumor pathology, anatomical
complexity, and patient-specific factors remains essential in achieving optimal resection and
minimizing morbidity.
