abstract
To test the hypothesis of crossed cerebro-cerebellar language dominance (Mari€ en, Engel-
borghs, Fabbro, & De Deyn, 2001) in atypical populations, the pattern of cerebral and
cerebellar language organization in a right-handed woman with a large porencephalic cyst
in the left temporal lobe with no secondary clinical neurological symptoms was studied by
means of an fMRI-language paradigm. Extensive neuropsychological examinations were
performed to formally rule out cognitive dysfunctions. The fMRI task, consisting of a covert
controlled oral word generation task, disclosed a pattern of bilateral activity in the frontal
language areas, slightly more pronounced in the left hemisphere, and unilateral activation
of the left inferior and superior temporal and supramarginal gyrus. This pattern of
supratentorial activations was reflected at the infratentorial level by bilateral activations in
the posterior lobe of the cerebellum with slightly more activity located in the right cere-
bellar hemisphere. This pattern of bilateral cerebral and cerebellar activation seems to
confirm that the distribution of supratentorial language dominance is intrinsically re-
flected at the level of the cerebellum. Bilateral frontal language representation might be
the consequence of neurofunctional compensation for the structural anomaly affecting
eloquent brain regions resulting in an operational inefficiency of the neural network
subserving language in the left hemisphere.
