Tour 1: Next/Previous/Start: This tour will examine the left parietal lesion, found at biopsy to be an anaplastic astrocytoma. First, note that the T2-weighted image shows a poorly circumscribed mass with a core of mixed high and low signal, a rounded periphery of higher signal, and a component of infiltrating edema, appearing as somewhat lower signal. The tumor appears to be centered in white matter underlying the left post-central gyrus.
