ABSTRACT
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.

A patient with cervical lymphoma received chemotherapy and radiation to the neck. He later presented with crescendo transient ischemic attacks. Angiography demonstrated bilateral cervical carotid stenosis, which was presumed to be the result of previous radiation therapy. Percutaneous transluminal angioplasty with balloon dilation of the symptomatic lesion resulted in an immediate cessation of the patient's transient ischemic attacks. Nine months later, he developed a symptomatic cervical carotid stenosis of the contralateral carotid artery, which also was treated successfully with angioplasty, resulting in a good clinical outcome. The patient has experienced no further ischemic events in the 2 years after treatment.
