title: Bilateral thalamic infarcts presenting as acute pseudobulbar palsy.
abstract: A 28-year-old, previously healthy, normotensive woman suddenly developed an acute pseudobulbar palsy with dysarthria, dysphagia, hypernasal voice and mild right arm paresis. Extensive laboratory investigations excluded all other possible causes of acute pseudobulbar palsy (neoplastic, inflammatory, demyelinative, myasthenic) and an MRI study demonstrated bilateral isolated thalamic infarcts. Oral contraceptives and smoking were the only possible stroke risk factors found and cerebral diaschisis the most tenuous explanation proposed. To our knowledge, this is the first report indicating that bilateral thalamic infarction on specific nuclei could be manifested as acute pseudobulbar palsy.
