  • Title: Tractography demonstrates dentate-rubro-thalamic tract disruption in an adult with cerebellar mutism.
    Author: van Baarsen K, Kleinnijenhuis M, Konert T, van Cappellen van Walsum AM, Grotenhuis A.
    Journal: Cerebellum; 2013 Oct; 12(5):617-22. PubMed ID: 23546861.
    Abstract:
    A 55-year-old female is presented with transient cerebellar mutism caused by a well-circumscribed left pontine infarction due to postoperative basilar perforator occlusion. Although conventional T2 imaging shows a well-demarcated lesion confined to the pontine region, diffusion tensor imaging shows an asymmetry in fractional anisotropy in the superior cerebellar peduncle. This supports the general hypothesis that cerebellar mutism is caused by functional disruption of the dentate-rubro-thalamic tract. Correlating postoperative anatomic changes to a heterogenic clinical syndrome remains challenging, however.
