Comparative StudyCarotid artery and jugular vein invasion of oral-maxillofacial and neck malignant tumors: diagnostic value of computed tomography.
This study aimed to disclose the diagnostic value of computed tomography (CT) images in detecting carotid artery and jugular vein invasion by oral-maxillofacial and neck malignant tumors. Study design Forty-three patients (44 tumors) who had had enhanced CT examination before surgical treatment of oral-maxillofacial and neck malignant tumors were evaluated. The CT manifestations of all tumors were retrospectively compared with the surgical findings. ⋯ Various CT findings are of value in the diagnosis of oral-maxillofacial and neck malignant tumors that affect the carotid arteries and jugular veins. Comparatively, the signs of compression and deformation of the CCA or ICA, segmental obliteration of the JV, undefined CCA or ICA wall, and fat or fascial plane deletion between a tumor and the CCA or ICA may be valuable in diagnosing ICA and JV invasion, although accurate diagnosis of CCA or ICA involvement by the oral-maxillofacial and neck malignant tumors remains difficult.
