DIAZ NEGRILLO, Antonio. Oculopharyngeal muscular dystrophy. Presentation of a peculiar case and importance of electromyographic findings. Acta Neurol Colomb. [online]. 2016, vol.32, n.1, pp.67-71. ISSN 0120-8748.

Oculopharyngeal Muscular Dystrophy is a rare genetic disorder characterized clinically by ptosis and deglutition difficulties. This work aims to give a detailed description of a particular case highlighting the relevance of the electromyographic findings in addition to a comprehensive literature review on the topic. Clinical, neurophysiological and molecular study of 82 years old patient referred to Clinical Neurophysiology Unit for progressive bilateral ptosis and dysphagia. The electromyographic study aimed the existence of a facial myopathy prevalence and molecular study confirmed the existence of a pathological expansion of 12 repetitions in the poly-alanine tract PABPN1 gene. Conclusions: Oculopharyngeal Muscular Dystrophy is an underdiagnosed disease that may go unnoticed by simulating other pathological processes. A rigorous neurophysiological study is essential to conduct a suspected diagnosis and to guide further molecular diagnostics.

Keywords : Oculopharyngeal Muscular Dystrophy; Myopathy; Electromyography.
