Abstract

Although clinical syndromes of visual–spatial neglect have been well described in adults, clinical features of neglect associated with subcortical dysfunction are infrequently reported in children and have not been described in detail. Unilateral visual–spatial neglect in a 7-year-old male following removal of a right subcortical juvenile pilocytic astrocytoma is reported. Preoperative baseline neurocognitive assessment of the patient established intact attentional and intellectual functioning. Postoperatively visual–spatial neglect was observed that was not accounted for by the patient's visual field deficit. Consistent with classic features of attentional neglect, increases in attentional demands led to greater errors in performance. The risk of unilateral neglect following resection of subcortical tumors that abut the thalamus or disrupt thalamo-cortical projections was confirmed in a retrospective analysis of patients referred for neurocognitive testing at our site. It was concluded that the ventral thalamus may play a role in visual–spatial attention early in development.
