A case of internal carotid artery dissection presenting as delayed right hemilingual paresis after blunt craniocervical trauma is presented. Diagnosis is discussed with emphasis on MR and MR angiographic findings. Mechanisms of injury and lower cranial nerve palsy are also briefly discussed.
A case of isolated parenchymal venous varix not seen on angiography is reported. CT demonstrated a well-defined cystic lesion with peripheral enhancement deep within the left temporal lobe. MR demonstrated a high-signal-intensity lesion with hemosiderin rim.
