abstract = {In the past, the eloquent areas could be deliberately
localised by the invasive Wada test. The very rare cases of
dissociated crossed speech areas were accidentally found
based on the clinical symptomatology. Today functional
magnetic resonance imaging (fMRI)-based imaging can be
employed to non-invasively localise the eloquent areas in
brain tumour patients for therapy planning. A 41-year-old,
left-handed man with a low-grade glioma in the left frontal
operculum extending to the insular cortex, tension
headaches, and anomic aphasia over 5 months underwent a
pre-operative speech area localisation fMRI measurement,
which revealed the evidence of the transhemispheric
disposition, where the dominant Wernicke speech area is
located on the left and the Broca’s area is strongly
lateralised to the right hemisphere. The outcome of the Wada
test and the intraoperative cortico-subcortical stimulation
mapping were congruent with this finding. After tumour
removal, language area function was fully preserved. Upon
the occurrence of brain tumours with a risk of impaired
speech function, the rare dissociate crossed speech areas
disposition may gain a clinically relevant meaning by
allowing for more extended tumour removal. Hence, for its
identification, diagnostics which take into account both
brain hemispheres, such as fMRI, are recommended.},
