Magnetic resonance imaging scan showed a hypodense area in the right temporal region, with contrast enhancing solid as well as large cystic components (Figure 1).
Spindled portion of the tumor, the cells have obviously eosinophilic cytoplasm and glial appearance

The neoplasic cell population was heterogenous, composed of spindle-shaped astrocytes with a fascicular arrangement (Figure 2).
GFAP is strongly positive in the glial portion of the tumor, but negative in blood vessel and mesenchymal cells in the desmoplastic areas

These cells show intense immunoreactivity for GFAP (Figure 3).
Neuronal portion of tumor, cells range from atypical ganglionic cells to small polygonal cell types

Scattered ganglion cells with copious cytoplasm and irregular nuclei were also observed, indicating neuronal differentiation (Figure 4).
Synaptophysin is positive in ganglion cells
