Thorough familiarity with the anatomy of the neck depicted in axial sections is fundamental to the interpretation of computed tomography (CT) scans. Fifteen consecutive sections are selected at 1 cm-intervals beginning at the level of the nasopharynx and extending down to the level of the thoracic inlet. Each scan is referenced to a profile drawing of the neck. Each CT scan is reproduced in line drawing, which is labeled for major organs and discrete structures appearing in that section. Twelve representative cases illustrate the usefulness of CT in the evaluation of neck masses by documenting tumor size, location and relationship to adjacent structures. Intravenous contrast improves recognition of vascular structures and distinguishes lymph nodes from blood vessels. The location and relative density of lesions facilitate their specific identification. Demineralization of bone and cartilage is accurately documented in the illustrative cases. Symmetry is the key to the interpretation of subtle pathologies.
