These originate from posterior portion the velum interpositum or falcotentorial union can present different relationships with vital neuroanatomical structures. The surgical treatment is not well established literature, due necessity validating criteria for approach discussion risks obtain radical resections.Case descriptionIt case report 41-year-old man FTM, who was admitted progressive paresis left lower limb last one year as only neurological symptom. A computed tomography (CT) realized, revealing solid mass region, causing hydrocephalus. After that, brain magnetic resonance imaging (MRI) showed inside third ventricule contact dural junction. patient submited subtotal tumor resection by an throught occipito-transtentorial acess.CommentsThe clinic FTMs varies headaches (the most common symptom), ataxia, personality changes bradpsychia homonymous hemianopsia. There exists four types FMTs according Boussioni classification, which based on location and, this case, type I, originated cerebral falx displaced venous system inferiorly. This classification it’s important guide decision approach. objective relieve solve neurological/clinical symptoms acquire tissue sample histological diagnosis. Some approaches be done these but transtentorial/transfalcine occipital frequently used meningiomas, especially I IV FTMs.ConclusionThe choice essential effective FTM tumor, analysed help tests. success reduce defict patient.
