title: [Aquired stuttering in addition to a recurrence of developmental stuttering caused by brain tumor in the corpus callosum].
abstract: We reported a 66-year-old right-handed man, in whom developmental stuttering had almost been cured previously, who suffered a brain tumor. He developed not only left hemiparesis but also speech dysfluency such as acquired stuttering and aphasia. MRI showed a brain tumor in the body of the corpus callosum. The main feature of his stuttering was repetition of syllables. His stuttering was associated without secondary phenomena such as tongue clicking. His stuttering demonstrated no adaptation benefit and no consistency effect. These results suggest that the stuttering in this patient might have characteristics of both developmental and acquired stuttering, which in turn may suggest that after brain tumor, acquired stuttering occurs in addition to a recurrence of developmental stuttering.
