    Clinical history is characteristic for cavernous sinus meningiomas. CT scans are sensitive for small lesions, while vascular patterns aid in locating larger ones, guiding subtotal removal and radiotherapy.

    Area of Science:

    • Neurosurgery
    • Neuroradiology
    • Oncology

    Background:

    • Cavernous sinus meningiomas present characteristic clinical histories.
    • Accurate diagnosis and surgical planning are crucial due to the complex anatomy of the cavernous sinus.
    • Complete tumor resection is often unfeasible because of the tumor's location.

    Purpose of the Study:

    • To analyze clinical and radiological findings in 12 cases of cavernous sinus meningiomas.
    • To evaluate the efficacy of CT scans and carotid angiography in diagnosing these tumors.
    • To determine optimal treatment strategies, including surgical approaches and radiotherapy.

    Main Methods:

    • Retrospective analysis of 12 surgically treated cavernous sinus meningiomas.
    • Comparison of CT scan and carotid angiography sensitivity in lesion detection and characterization.

  • Review of surgical outcomes and radiotherapy indications.

    • Main Results:

    • CT scans demonstrated higher sensitivity than carotid angiography for detecting small cavernous sinus meningiomas.
    • Vascular supply patterns on imaging were key for identifying the location of larger lesions.
    • Near-definitive diagnosis was achievable with both CT and angiography; however, complete surgical removal was rarely possible.

    Conclusions:

    • Subtotal microsurgical removal via a subtemporal approach is the current best treatment for cavernous sinus meningiomas.
    • Radiotherapy is recommended for incompletely resected tumors.
    • Advancements in neurosurgical techniques, like the Cavitron, may enable more radical approaches in the future.
