Ganglioneurocytoma mimicking a malignant tumor: case report with a literature review of the MRI appearance of neurocytomas and gangliogliomas.
A 14-year-old girl presented with symptoms of increased intracranial pressure after her head was squeezed at a party. MRI demonstrated a mass that was hypointense to brain on T1WI and heterogeneous in signal on PD and T2WI; compression of the ventricle, midline shift, and mild ventriculomegaly also were present. Contrast enhancement was extensive and heterogeneous, mimicking a malignant tumor. Neuropathology revealed a ganglioneurocytoma.
