title: [Crossed aphasia in a dextral patient--a case of sensory aphasia due to a right hemispheric lesion].
abstract: An extremely rare case of sensory aphasia due to a right hemispheric lesion in a 61-year-old, right-handed male is reported. He manifested jargon aphasia, constructional apraxia and ideational apraxia after an operation for right temporo-parietal cerebral hemorrhage. Standard language test of aphasia (SLTA) administered 6 months after the onset revealed disturbance of verbal comprehension and repetition, fluent jargon with many paraphasias and paragraphias. The brain CT, MRI and IMP-SPECT disclosed right temporo-parietal and angular lesions. There are two other reported cases of right posterior lesion (Puels et al. 1982, Habibs et al. 1983) accompanied by symptoms similar to those in this case, e.g., jargon aphasia, paragraphia and apraxia, and in these cases as well the right deep hemispheric lesion encompassed Wernicke's area. It is suggested that the right and left brain functions are reversed in this patient, because the symptoms of the dominant hemisphere such as sensory aphasia, constructional apraxia, and ideational apraxia were associated with the lesion of the right hemisphere.
