Objective: To investigate the right hemispheric speech perception capabilities of an adult right-handed patient with seizures.Methods: Consecutive, unilateral, intracarotid sodium amobarbital injections and left hemispheric electrical interference mapping were used to determine lateralization and localization of speech perception, measured as syllable discrimination.Results: Syllable discrimination remained intact after left and right intracarotid sodium amobarbital injections. Language otherwise strongly lateralized to the left hemisphere. Despite evidence of bilateral speech perception capabilities, electrical interference testing in the left posterior temporal lobe impaired syllable discrimination.Conclusions: The results suggest a functionally symmetric, parallel system in the adult brain with preferential use of left hemispheric pathways for speech perception.

Amygdalohippocampectomy (AH) is an accepted surgical option for treatment of medically refractory mesial temporal lobe epilepsy. Operative approaches to the amygdala and hippocampus that previously have been reported include: the sylvian fissure, the superior temporal sulcus, the middle temporal gyrus, and the fusiform gyrus. Regardless of the approach, AH permits not only extirpation of an epileptogenic focus in the amygdala and anterior hippocampus, but interruption of pathways of seizure spread via the entorhinal cortex and the parahippocampal gyrus. The authors report a modification of a surgical technique for AH via the parahippocampal gyrus, in which excision is limited to the anterior hippocampus, amygdala and parahippocampal gyrus while preserving the fusiform gyrus and the rest of the temporal lobe. Because transparahippocampal AH avoids injury to the fusiform gyrus and the lateral temporal lobe, it can be performed without intracarotid sodium amobarbital testing of language dominance and language mapping. Thus the operation would be particularly suitable for pediatric patients in whom intraoperative language mapping before resection is difficult.

Intracranial infectious aneurysms (IIAs) are a rare subgroup of intracranial aneurysms. Often erroneously termed mycotic aneurysms, these lesions most often result from infectious endocarditis and involve the distal anterior cortical circulation. Diagnosis typically follows headaches or septic infarcts, although increasing numbers of lesions are found incidentally, during screening protocols for infectious endocarditis. Open surgical treatment was previously the mainstay of treatment; however, these IIAs are often fusiform and quite fragile, making open surgical obliteration difficult and typically requiring lesion trapping. Current treatment techniques more commonly involve endovascular coil embolization or parent vessel occlusion. Many of these lesions occur distally, in or around the eloquent cortex, making embolization potentially dangerous. We present cases that highlight the use of super-selective provocative testing with sodium amobarbital and lidocaine, to help clarify and predict the risk of parent vessel occlusion in IIAs located in the eloquent cortex.
