It was a true pleasure to host @DrShaanRaza at SNOLA Meeting 2026. His insights on chordoma management added great value.
This collaboration, in partnership with the @ChordomaFDN , underscores the importance of bringing together global expertise to advance care in neuro-oncology

Team effort, full house.

These images capture what SNOLA Meeting 2026 truly was: a gathering of leading voices in neuro-oncology from around the world, culminating in what has become the largest conference in Latin America in our field.

Proud to share this work developed under my supervision by a talented team of medical students from the University of Campinas.

We analyzed surgical approaches for insular gliomas through the lens of Berger–Sanai classification.

Very happy to close an important chapter of my academic journey.

Over the past few years, my PhD research resulted in five published papers exploring different aspects of pediatric posterior fossa tumors!

I am deeply grateful to all collaborators who were part of this journey!

San Diego delivered another unforgettable NASBS meeting — reconnecting with old friends, meeting inspiring colleagues, and learning from the best.

Honored to present 1 operative video, 1 oral presentation, and 4 posters.

Happy to share the latest publication from the main study of my PhD research in Child's Nervous System.

We analyzed predictors of postoperative hydrocephalus and shunt dependence in children with posterior fossa tumors.

Published in @NeurosurgeryCNS!
During my research fellowship at @PittNeurosurg, we compared the far-lateral, far-medial, and contralateral transmaxillary approaches to the jugular tubercle - each with unique anatomical advantages for complex skull-base surgery.

Excited to share our new publication in Child’s Nervous System! @SpringerNature

Together with a multidisciplinary team, we compared proton beam radiation vs photon radiation for pediatric medulloblastomas in a systematic review & meta-analysis.

In the Journal of Neuro-Oncology, the Stanford neurosurgery team studied PIK3CA-mutated meningiomas looking at targeted therapy approaches.

[NEJM Evidence @NEJMEvidence]

How do we make sense of two “negative” trials in @NEJM and a “positive” meta-analysis of the two trials in NEJM Evidence? @emil_hs and @FralickMike share some insights in this editorial: https://t.co/KNmYhXEt6b

The Brazilian Skull Base Surgery Meeting in Florianópolis has come to an end! An incredible opportunity to learn from leading experts in the field, along with unforgettable moments shared with friends, mentors, and inspirations in skull base surgery.

[Cleiton Formentin, MD, PhD @cleitonfmd]

@ChampagnePierr2 @joao_p_almeida @ronconi_Daniel @martinbcoutinho It was wonderful to see you, my friend. Congratulations on your outstanding work!

Check out our recently published paper on a fast-track neuropsychological assessment protocol designed for glioma patients selected for awake craniotomies.

The test consists of 10 subtests and is fully available as supplementary material.
