A growing body of literature indicates that the occurrence of thalamic lesions could lead to various dysfunctions, such as somatosensory disturbances, hemiparesis, language deficits, and movement disorders. However, clinical cases describing the coexistence of these types of manifestations have not been reported. Herein, we report a patient who exhibited these rare complications secondary to thalamic hemorrhage.
A 53-year-old right-handed man experienced sudden left hemiparesis, numbness of the left side of body, and language alterations due to an acute hemorrhage located in the right basal ganglia and thalamus 18 mo ago. Approximately 17 mo after the onset of stroke, he exhibited rare complications including dysphasia, kinetic tremor confined to the left calf, and mirror movement of the left arm which are unique and interesting, and a follow-up computed tomography scan revealed an old hemorrhagic lesion in the right thalamus and posterior limb of the internal capsule.
Hypophonia may be a recognizable clinical sign of thalamus lesions; thalamus injury could cause tremor confined to the lower extremity and mimicking extremity movements.
Core Tip: Clinical cases describing the coexistence of multiple manifestations secondary to thalamic damage have not been reported. We report a patient who exhibited rare complications secondary to thalamic hemorrhage. Especially, the manifestations including dysphasia, kinetic tremor confined to the left calf, and mirror movement of the left arm are unique and interesting. This case provides new insights into thalamus damage. Hypophonia may be a recognizable clinical sign of thalamus lesions, which could help with lesion localization; thalamus injury could cause tremor confined to the lower extremity and mimicking extremity movements.
