In addition, increase in size is not always pathologic; some nodes are bigger than others normally (e.g compare jugulodigastric nodes to mesenteric nodes), and reactive nodes are a healthy response and do not imply pathology of the node it… Author : Anthony P. Yudd, Jeffrey S. Kempf, James S. Goydos, Theodore J. Stahl, Richard S. Feinstein Swollen cervical lymph nodes can be a normal occurrence. Lymphadenopathyis quite common, and it can be very difficult to differentiate malignant lymphadenopathy from reactive nodal enlargement. The lower border of station 1L is the clavicles bilaterally and, in the midline, the upper border of the manubrium. The deep cervical chain of nodes follows the internal jugular vein so, after contrast administration, lymphadenopathy can often be seen against the lucent (fatty connective) tissue surrounding the common carotid artery and internal jugular vein.

The carotid bifurcation is the point at which the common carotid artery terminates. Various criteria have been proposed to predict metastatic involvement of a cervical lymph node on CT and MR: Some studies compared the relative value of these different features, finding that minimal axial (short-axis) diameter was a better classifier for metastatic disease than maximal axial (long-axis) diameter or longest coronal (longitudinal) diameter 1,5. 40 (6): 1049-1054. neck lymph node metastasis (radiologic criteria), cervical lymphadenopathy (radiologic criteria).
