Transient mutism is a rare but reversible complication following a posterior fossa approach to cerebellar tumors. The mechanism of such transient mutism seems to be a complex of different factors acting on reticular-spinal system located in midbrain, instead cortico-spinal fibres are not involved. After the first case noted by Hirsch et al. 33, 87 cases of transient mutism in children affected with posterior fossa tumors were found in literature, with an incidence of 15%. To further characterize posterior fossa syndrome (PFS) we reviewed 18 children with posterior fossa tumors who underwent surgical resection; we documented 2 cases of PFS (11%). Age ranged from 8 to 14 years old, median age 11 years. Mutism had a latency range of 42,5 hours (range 0-72 hours) and a mean duration of 100 days (range 90-110). In addition to speech impairment, affected patients often exibit a spectrum of characteristic neurobehavioral deficits which may include eating dysfunctions, emotional lability, impaired eye opening, ataxia and dysmetria.
