Respected Member of the International Meningioma Society,

With this mail we wish to invite you to the 13th International Meningioma Society meeting which will take place on May 8-11th in Istanbul-Turkey.

The International Meningioma Society was formed to foster advancements in the clinical care and research of meningiomas, aiming to provide the best possible care. The Society was established in September 2008 following a series of inspiring meetings that began with the first “International Symposium on Skull Base Meningiomas” which was organized by Prof Rudolf Fahlbusch in Bamberg-Germany in 1992 and the “First international workshop on Surgery of the intracranial venous system” organized by Prof Akira Hakuba in Osaka-Japan in 1994. These gatherings brought together neurosurgeons, radiation oncologists, basic research scientists and epidemiologists from all around the World to collaborate on understanding meningiomas better. The decision to form a society was made during the fifth meeting of these international gatherings, highlighting a collective desire to organize efforts in meningioma research and care, ensure the continuity of these important meetings, and promote international communication and collaboration. Obviously, these meetings of the International Meningioma Society form the glue that holds together the spirit of the society. Keeping with this tradition, this 13th IMS meeting will feature all the novelties in Meningioma Treatment and Research that even the most experienced of the field are eagerly waiting for.

The meeting is supported, among many prestigious Societies and Academies, by the Rhoton Society, which is organizing a pre-meeting course on “intracranial venous system”, to honor the tradition of former Meningioma Society meetings. Among the supporting international societies are the World Academy of Neurological Surgery, the Turkish Neurosurgical Society, the Turkish Neurosurgical Academy, and the Southeast Europe Neurosurgical Society.

In addition to a full scientific program, the 2025 Istanbul meeting will take place in one of the most scenic and chic Hotels in Istanbul, the Hilton Bosphorus. The meeting will take place during the most enjoyable spring bloom season of Istanbul and will offer a rich social program

We will be honored to have you with us in this one in a lifetime event.

Dear Colleagues,

It is my honor and privilege to invite you to “Rhoton 3D Course: Microsurgical and Endoscopic Anatomy and Approaches for Skull Base Meningiomas with special emphasis on Cerebral Venous System” on the 8th of May 2025.

Although the title of the initial meetings was “Cerebral Venous System and Meningiomas”, after the establishment of the International Meningiomas Society, the focus shifted towards Skull Base Surgery and Meningiomas. In this regard, our premeeting course primarily aims to honor the roots of the Rhoton’s influence on microsurgical anatomy of the skull base and reemphasize the importance of relevant cerebral venous network. Our additional objective is to follow Dr. Rhoton’s goal to improve the neurosurgical care of patients with skull base pathologies by delineating anatomical step-by-step 3D dissections for complex skull base approaches to the neurosurgeons.

This course follows the neuroanatomical heritage paved by Prof. Albert L. Rhoton, a great researcher and devoted educator, to extend the imperative knowledge of endoscopic and microsurgical anatomy for the surgery of the Skull Base. The course will be beneficial for not only neurosurgeons specializing in the skull base field, but for all neurosurgeons and residents looking to expand their knowledge on skull base surgery. The course will be held on the 8th of May 2025 followed by the Congress on Meningiomas, in the city of Istanbul. As the organizing committee and members of the International Meningioma Society, it would be our pleasure to see you join us in our lovely city with its rich historical heritage where the Asian and European parts of Turkey meet.

Best regards,
Prof. Dr. Necmettin Tanrıöver,
Course Director
