Suppurative lymph node. Patient presenting with fever, sore throat, cough, and a palpable left neck mass. a Axial contrast-enhanced CT image demonstrates an enhancing left deep cervical chain lymph node (white arrows), with a hypoattenuating center (star). The left internal carotid artery (IC) is medially displaced. b Axial contrast-enhanced CT image 3 days later demonstrates rupture (arrows) of the suppurative node. Note the preserved fat planes in the normal right carotid space (dotted circle). c Sagittal CT image demonstrates fluid tracking along the left carotid space from the lymph node rupture (arrows)
