“…It is important to note that distinct Hebrew naming and reading sites were also found in areas distant from his first resection --such as in the middle frontal and angular gyri for naming and the supramarginal gyrus for reading. These results suggest that the distinct sites found for L2 are not solely due to the functional reorganization of the secondary language but represent the detection of genuine distinct sites that is consistent with other cortical stimulation studies of bilinguals 26,33,42,45,46,54 .…”

✓A bilingual pediatric patient who underwent tumor resection was mapped extraoperatively using cortical stimulation to preserve English and Hebrew languages. The authors mapped both languages by using 4 tasks: 1) English visual naming, 2) Hebrew visual naming, 3) read English/respond Hebrew, and 4) Hebrew reading. Essential cortical sites for primary and secondary languages were compared, photographically recorded, and plotted onto a schematic brain of the patient. Three types of sites were found in this patient: 1) multiuse sites (multiple tasks, both languages) in frontal, temporal, and parietal areas; 2) single-task sites (1 task, both languages) in postcentral and parietal areas; and 3) single-use sites (1 task, 1 language) in frontal, temporal, and parietal areas. These results lend support to the concept that bilingual patients can have distinct cortical representations of each language and of different language tasks, in addition to overlapping or shared sites that support both languages and multiple tasks.

“…In an attempt to gain a better anatomical understanding of how multiple languages are represented in the human brain, Roux and Trémoulet [14 ]studied 12 bilingual patients who underwent surgery for brain tumours, during which they mapped cortical language sites by using electrostimulation. Strict overlapping of language areas (for all language tasks) was found in 5 patients, whereas the remaining 7 had at least one area that was language specific and sometimes task specific.…”

Johann Gesner in 1770 probably provided the first description of dissociation in reading ability in different languages in a bilingual patient, who after brain damage was able to read Latin but not German. Clinical studies have since shown that bilingual ‘aphasics’ do not necessarily manifest the same language disorders with the same degree of severity in both languages. Superficially, different case findings indicate instances of shared and divergent representation of components of language in the bilingual brain. This paper considers a selection of many empirical studies, which have failed to reconcile the parallel recovery of language in many reported bilingual aphasiacs and the differential recovery in others. It reviews Pitres’ rule (recovery of the most used acquired language) and Ribot’s law (recovery of the native language) that are important concepts during recovery and rehabilitation of bilingual aphasiacs.

“…Previous studies of language areas in bilingual patients have found the cortical areas for multiple languages were located in the temporo-parietal cortex and in the frontal cortex with individual variability. 5,6,12,13) In the present patient, one of the language areas was located in the MITC. In various case series, naming sites in the temporal lobe were predominantly found in the superior and middle temporal gyri.…”

“…6) The language areas are located in the frontal and temporal cortices with individual variability in both monolingual patients and bilingual patients. 5,7,12,13) Furthermore, the presence of a language area in the inferior temporal cortex (ITC) is not usually detected by intraoperative mapping for glioma surgery as well as during the removal of other tumors and in epilepsy surgery. 10,12) We report a patient with unique language areas identified by intraoperative mapping.…”

Fig. 1 Upper row: T 1 -weighted magnetic resonance (MR) images with gadolinium showing a small ring-enhanced mass in the left superior temporal lobe. Lower row: T 2 -weighted MR images revealing the presence of a hyperintense area in the temporal lobe measuring 6 cm in maximal diameter. 256 CASE REPORT AbstractA 40-year-old bilingual man underwent removal of glioblastoma multiforme with intraoperative language mapping, mainly using the picture-naming and auditory responsive-naming tasks under cortical stimulation. Multiple language areas were identified, including one located in the middle of the inferior temporal cortex (ITC). Individual mapping for glioma patients must be performed because language areas might be located in various and unexpected regions, including the ITC.
