Endoscopic occipital transtentorial transrecess approach for resection of a challenging midbrain-thalamic cavernous malformation: illustrative case.

Key Points

• This research aims to assess the efficacy and safety of the endoscopic occipital transtentorial approach for removing cavernous malformations located in the midbrain-thalamus.
• Utilized EOTTA for access to the cavernous malformation.
• Employed diffusion tensor imaging (DTI) for guided neuronavigation.
• Incorporated endoscopic magnification during the procedure to enhance visualization.
• Focused on minimizing cortical retraction and protecting critical neural pathways.
• The endoscopic approach allowed for safe resection of the targeted cavernous malformation.
• Reduced risk of injury to critical tracts in the brain.
• Demonstrated effective outcomes with minimal cortical retraction.
