Visual Puzzles, Figure Weights, and Cancellation: Some Preliminary Hypotheses on the Functional and Neural Substrates of These Three New WAIS-IV Subtests
Figure 4
Participant no. 4 with a right thalamic lesion. The MRI image in (a) depicts a calcified third ventricular mass occluding the third ventricle which was subsequently resected. Lateral ventricular dilation is evident. The CT image in (b) depicts resolution of ventricular dilatation subsequent to tumour resection and reopening of the cerebrospinal fluid cisterns. However, (b) shows a right posterior thalamic ischemic infarct appearing two weeks after resection of the third ventricular tumour.
