ABSTRACT
Hypophonia is a neurological sign usually seen after brainstem or peripheral damage, either at the recurrent laryngeal nerve or vocal cord level. However, it has been described as a sign of supratentorial strokes in a few studies, specifically when anterior and ventral thalamic involvement is reported. In addition, it is a prominent sign of other neurological disorders such as Parkinson disease and other extrapyramidal conditions. We describe a case of hypophonia secondary to a left thalamic hemorrhage, after a careful search of other potential causes of this deficit, and we discuss the underlying neuroanatomical circuits.
