title: CT angiography before embolization for hemorrhage in head and neck cancer.
abstract: We present a patient with advanced head and neck carcinoma and a bleeding pseudoaneurysm diagnosed by means of CT angiography; this was not apparent on conventional digital subtraction angiograms. The information provided by CT angiography facilitated rapid identification of the pseudoaneurysm and treatment with embolization. CT angiography may be helpful before embolization in cases of hemorrhage in head and neck cancer.
