Cerebellomedullary ganglioglioma: CT and MR findings.

We present a case of cerebellomedullary ganglioglioma in a young child with indolent clinical symptoms. CT demonstrated a region of hypodensity with central contrast enhancement in the right cerebellar hemisphere and the inferior peduncle. On MR the lesion was iosintense on T1-weighted images with fairly homogeneous enhancement with gadolinium, and of high signal intensity on T2-weighted images.
