Crossed aphasia elicited by intraoperative cortical and subcortical stimulation in awake patients

摘要: Object Crossed aphasia (aphasia resulting from a right hemispheric lesion among right-handed patients) is rare. The authors describe for the first time transient crossed elicited by intraoperative electrostimulation of both cortex and white matter pathways in awake patients. Methods Three adults underwent surgery right-sided glioma. Because slight language disorders occurred during partial seizures or were identified on preoperative cognitive assessment, with activations detected functional MR imaging 1 patient, craniotomy was performed using cortico-subcortical electrical mapping. Results Transient disturbances stimulating discrete cortical areas (inferior frontal gyrus posterior part superior temporal gyrus) frontooccipital fasciculus arcuate fasciculus). A subtotal resection achieved all cases, according to boundaries. Postoperati...
