Radiologic, cytologic and morphologic appearance of the tumor. 1: This computed-tomographic scan of the patient's cerebral mass shows a large cystic mass with peripheral enhancement at the solid portion which attached to the overlying dura; 2: In addition to scattered individual cells, variably sized clusters of neuronal cells were identified, all composed of cells with eccentrically located, occasionally binucleated hyperchromatic nuclei and abundant unipolar cytoplasm [original magnifications x400]; 3: Occasional neuronal cells were binucleated (3a) while others showed bland nuclear features (3b) [original magnifications x400]; 4: Scattered astroglial cells with more convoluted nuclear contours and less cytoplasm were also present. [original magnifications x400]; 5: Typical histologic appearance of desmoplastic infantile ganglioglioma, showing scattered ganglion cells in a desmoplastic and fibroblastic, vaguely storiform background (original magnification x200, inset x400)

He was brought to the emergency room where an emergent computed tomographic scan showed a large left hemispheric cerebral mass (Figure 1-1) with an underlying cystic component and a more superficial area of bright enhancement; the rest of the brain showed massive edema.
