Case Report: A 71-year-old man had a history of NPC treated with radiation therapy 26 years ago. He
was admitted to the hospital because of minor ischemic stroke and tarry stool. The carotid duplex
sonography disclosed severe stenotic lesion in the proximal right internal carotid artery. A subsequent
recurrent stroke on day three associated with nasal cavity bleeding resulted in an endotracheal
intubation. Another episodic of massive epistaxis occurred on day 10 caused hypovolemic shock.
Pseudoaneurysm of the left internal carotid artery was found by emergent angiography and was
immediately obliterated by endovascular treatment with microcoils and glue.
