Abstract:
A 13-year-old patient developed complete mutism and buccofacial apraxia following toxic vasculitis due to a yellow scorpion sting. Language functions were preserved. A CT scan disclosed mainly biopercular infarcts. It is suggested that the lost control of vocalization and speech is associated with biopercular lesions and that a preserved right opercular region can take over this function in the presence of damage to homologous left opercular region.
