Sudden benzodiazepine-induced resolution of post-operative pediatric cerebellar mutism syndrome: a clinical-SPECT study

Abstract

Post-operative pediatric cerebellar mutism syndrome (PPCMS) is a clinical syndrome arising from cerebellar injury and characterized by absence of speech and other possible symptoms and signs. Rare reports described some benefit after administration of dopamine agonist therapy, but no treatment has proven efficacy. In this paper, we report on the dramatic, sudden resolution of PPCMS induced by midazolam administration in a boy who underwent posterior fossa surgery for choroid plexus papilloma of the fourth ventricle. In addition to clinical improvement, post-midazolam single-photon emission computed tomography also demonstrated amelioration of brain perfusion.
