The relationship between short-term memory impairment and sentence comprehension is explored in a right-handed patient with a focal temporoparietal lesion of the right hemisphere. The general clinical profile, as well as characteristics of the patient's immediate memory for word lists, suggests the occurrence of a mirror image crossed aphasia. Detailed analysis of the patient's ability to repeat and to comprehend sentences, however, indicates some important differences between this case and previously reported patients with short-term memory impairment. It is suggested that these differences, which may be related to an unusual pattern of neuroanatomical organization of cognitive functions, involve symptom dissociations with implications for models of normal language/memory interactions.
