Necrotic nasopharyngeal mucosa: an ominous MR sign of a carotid artery pseudoaneurysm.
Massive hemoptysis is not commonly seen in patients who have nasopharyngeal carcinoma. It most often is the result of both radiation therapy and skull base infection. We present a practical imaging approach by using MR imaging and conventional angiography that may facilitate the prevention of such life-threatening bleeding and help provide effective control of infection. With the aid of these studies, clinicians may be able to manage this condition with more confidence.
