• A 53-year-old hypertensive, converted left-handed man manifested aphasia after a right thalamic hemorrhage. The syndrome of mild, fluent aphasia, with naming difficulty and occasional paraphasic errors, but intact comprehension and repetition, is similar to that of previously reported patients with left thalamic lesions. The occurrence of aphasia after right thalamic hemorrhage suggests that right-hemisphere language dominance in left-handed subjects can extend even to the level of the thalamus.
