摘要：

WE REPORT A right-handed patient who developed a nonfluent aphasia after surgery for a right parietal arteriovenous malformation. Resting brain single-photon emission tomography displayed decreased regional cerebral blood flow only in the right hemisphere, with spared regional cerebral blood flow in the left hemisphere. Single-photon emission tomography performed after a language activation task (Boston Naming Task) showed a consistent area of increased regional cerebral blood flow in the right inferior and posterior frontal lobe, supporting a right hemisphere dominance for language. These results suggest a potential role for this noninvasive study in the evaluation of language lateralization.
