title: Bulbar and Limb Myorhythmia with "Smooch Sign": A Distinctive Movement Disorder in an Adult Patient with Reversible Anti-NMDA Receptor Encephalitis Associated with an Ovarian Teratoma.
abstract: Anti-N-Methyl-D-Aspartate receptor encephalitis is a recently described entity (Dalmau et al. 2007, 2008) that may present with a variety of complex movements in addition to other features (Kleinig et al. 2008). The purpose of our presentation of such a patient is twofold: (1) to characterize these complex oculo-oro-linguo-masticatory and limb movements with "smooch sign" as myorhythmia, based on a combined clinical and electrophysiological analysis (Masucci et al. 1984); and (2) to document possibly characteristic EEG evolution in the course of observation in our institution for three weeks from diffuse slowing to evolving rhythmic delta activity, which may represent a pattern of electrographic seizure activity.
