A 70-year-old man with hypertension initially presented with imbalance and dizziness and underwent magnetic resonance imaging (MRI), which demonstrated a 3.2 cm x 2.8 cm x 3.7 cm heterogeneously enhancing mass in the suprasellar region which extended to the posterior fossa resulting in mild mass effect on the midbrain and ventral pons and displacement of the optic chiasm [Figure 1].
(a) Ganglioid differentiation of the tumor. Arrows are pointing at ganglion cells. (b) Neurocytes (small round cells with round nucleus) with surrounding capillaries. The circle is showing an example of neurocytes.

These cells were intermixed with occasional large cells with large nuclei and prominent nucleoli resembling neurons or ganglioid cells [Figure 2].
