Aphonia as the only speech disturbance from bilateral paramedian thalamic infarction.
We examined a 55-year-old right-handed woman showing transient coma, amnesia, mild right hemiparesis, vertical gaze impairment and aphonia without aphasia. CT-scanning revealed bilateral paramedian thalamic infarction in the territory of the thalamo-subthalamic paramedian arteries. Aphonia may occur as a consequence of thalamic lesions, but until now it has not been described as an isolated speech disturbance.
