Carotid blowout syndrome with oronasal hemorrhage: magnetic resonance imaging findings.

Reports on magnetic resonance imaging (MRI) findings of CBS are limited in the relevant literature, probably because of the angiography priority of this complication. We describe MRI findings in a patient with nasopharyngeal carcinoma complicated with CBS.
