Diagnosis of lymphoepithelial carcinoma in parotid gland with three dimensional computed tomography angiography reconstruction: A case report.

Lymphoepithelial carcinoma (LEC) is an uncommon malignant neoplasm. Due to the complicated anatomical structure of the human head, standard imaging modalities including ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) scan remain limited in detection of salivary tumors. We used three-dimensional computed tomography angiography (3D-CT angiography) for the assessment and pre-operative surgical planning of facial fractures of a case with LEC. The study results demonstrated that 3D-CT angiography provided an insightful approach to preoperative evaluation in the treatment of salivary tumors.
