Cerebellar AVMs differ markedly from their supratentorial counterparts in that there are no perforating vessels involvement, drainage into the deep cerebral venous system, or presence of eloquent functional area except for the dentate nucleus. While Ya\u015fargil has classified cerebellar AVMs into seven subtypes according to their location, de Oliveira <jats:italic>et al<\/jats:italic>. have classified them using a more impactful grading system based on the size, location, and involvement of the dentate nucleus with the highest risk being III (size over 4 cm) C (mixed superficial and deep location) * (dentate involvement). In this extensive AVM with multiple arterial feeders from the SCA, AICA, and PICAs, preoperative embolization facilitates the safe surgical removal.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>We present the case of resection of de Oliveira <jats:italic>et al<\/jats:italic>. IIIC* cerebellar AVM highlighting the tenets of preoperative embolization, wide surgical exposure with an extended retrosigmoid approach, arachnoidal dissection of the SAC, AICA, and PICA feeders, parenchymal dissection with preservation of the dentate nucleus, and preservation of venous drainage until complete disconnection.
