• A novel taxonomy for cerebellar cavernous malformations (CMs) is proposed, introducing six distinct subtypes based on anatomical location.
• The study was conducted over a 25-year period and involved 143 cerebellar CMs treated microsurgically.
• The subtypes include suboccipital, tentorial, petrosal, vermian, tonsillar, and deep nuclear lesions.
• Favorable neurological outcomes were achieved in 91% of cases, with a mean follow-up of 37.4 months.
• Surgical approaches were guided by the CM subtypes, aiming to minimize tissue transgression and preserve function.
• Complete resection was achieved in 94% of cases, with no significant differences in outcomes between subtypes.
• The taxonomy aids in selecting craniotomy and approach to enhance patient safety and optimize outcomes.
