Mutisme cérébelleux après ablation d’un médulloblastome vermien chez un adulte

Gunshot Wound to the Posterior Fossa With a Transcerebellar Retromesencepahlic Bullet Path, Transient Mutism, and Unexpected Functional Recovery: The Pivotal, Energy-Absorbing Function of the Petrous Bone and Tentorial Leaflet

“…Though cerebellar mutism has most commonly been described in the context of fourth ventricular tumor resections, particularly when an incision is made in the vermis and in children with medulloblastoma [6], this syndrome has only been rarely reported in the setting of trauma (Table 1) and never previously as a result of a GSW to the head [7][8][9][10][11][12]. The exact pathophysiological mechanism of cerebellar mutism remains unclear, though it is generally agreed upon that damage to the cerebello-cerebral pathways is a major contributing factor [6,[13][14][15][16]. Moreover, injury to the cerebellar vermis, as in the present case, has been widely suggested as the underlying etiology, especially given that the vermis and adjacent paravermal areas are involved in the coordination of laryngeal functions [17,18].…”

Cerebellar Mutism Syndrome in Children and Adults

“…Speech was described as 'thick', cerebellar or ataxic, scanned or staccato, near normal or reduced in voice volume in nine patients (33.3%) (Moore 1969;D'Avanzo et al 1993;Bhatoe 1997;Coplin et al 1997;Dunwoody et al 1997;Sherman et al 2005;De Smet and Mariën 2012;Mariën et al 2013a). Follow-up information varying between 2 months (Kai et al 1997) and 4 years post-surgery (Adachi et al 2005;Akhaddar et al 2008) was provided for 21 of the 27 patients (77.8%) (Moore, 1969;Salvati et al 1991;D'Avanzo et al 1993;Coplin et al 1997;Dunwoody et al 1997;Kai et al 1997;Caner et al 1999;Ildan et al 2002;Sajko et al 2004;Adachi et al 2005;Sherman et al 2005;Akhaddar et al 2008;De Smet and Mariën 2012;Damodaran et al 2013;Gündüz et al 2013;Mariën et al 2013a;van Baarsen et al 2013;Manzano-Lopez Gonzalez et al 2015). Nine of the 27 patients (42.9%) (Moore, 1969;Dunwoody et al 1997;Kai et al 1997;Caner et al 1999;Ildan et al 2002;van Baarsen et al 2013;Adachi et al 2005;Sherman et al 2005;Akhaddar et al 2008) had normal speech at final follow-up.…”

Of the remaining patients, eight had dysarthric symptoms (Salvati et al 1991;Coplin et al 1997;Kai et al 1997;Ildan et al 2002;De Smet and Mariën 2012;Damodaran et al 2013;Gündüz et al 2013;Manzano-Lopez Gonzalez et al 2015) Depicted behavioral-affective symptoms included lethargy and confusion…”
