Description
Summary:Lesions located in the bilateral posterior incisural space are difficult to treat due to limited exposure. The classical approaches to this area are limited for lesions located bilaterally and especially when the lesion extends also below the tentorium as it may occur with meningiomas. Kawashima et al. reported, in anatomic studies, a new occipital transtentorial approach: the occipital bi-transtentorial/falcine approach, to treat such lesions. We present a patient with a large falcotentorial meningioma, located bilaterally in the posterior incisural space. The occipital bi-transtentorial/falcine approach allowed an excellent surgical exposure and complete tumor removal with an excellent patient outcome.Grandes lesões que ocupam bilateralmente o espaço incisural posterior são de difícil abordagem cirúrgica pelos acessos clássicos. Recentemente, Kawashima et al. descreveram, em peças anatômicas, uma modificação do acesso occipital transtentorial, o acesso occipital bitranstentorial-falcino, para abordagem de grandes lesões que ocupam bilateralmente o espaço incisural posterior. Retata-se um caso de grande meningioma falco-tentorial que ocupava o espaço incisural posterior bilateralmente. O acesso occipital bitranstentorial-falcino permitiu exérese completa da lesão sem déficit no pós-operatório.
