Figure 1: Detection of the largest lymph node in a patient with mucosal-based SCCa and neck lymphadenopathy by CT with IV contrast. Arrows demonstrate the longest axis of a selected “enlarged” lymph node within level IIA on (a) axial, (b) coronal, and (c) sagittal planes. The primary tumor was a left-sided oropharyngeal squamous cell carcinoma (SCCa). The selected lymph node shows partial central necrosis.
