Gross and microscopic lesions of corpus callosum and neighboring structures are common in severe closed head injury. Left limb apraxia after damage to corpus callosum has been reported in patients whose neocortical commissures were sectioned for relief of severe epilepsy and in patients affected by naturally occurring lesions either of vascular or neoplastic origin. Only few reports are found in literature to have split-brain syndrome or disconnection syndrome of traumatic origin. Here we present a patient with left-sided apraxia, agraphia, and tactile anomia with right-sided constructional disturbances after a severe head injury with corpus callosal bleed. Left-sided apraxia was profound on verbal command, visual presentation of an object, and imitation, but not during tactile presentation or the actual use of the objects. These data are consistent with left hemisphere dominance for praxis, which is almost absolute when the retrieval of the appropriate gesture requires a semantic analysis of the stimulus.
