The features considered to be predictive of malignant lymph node invasion include hypoechoic structure sharply demarcated borders rounded contour and a size greater than 10 mm. A right paratracheal lymph node is abnormal based on size and morphology.

The mass is 36x3x4 cm size and is round with well definedmargins.

Therefore patients with stage IV disease and those with tumor nodules outside the pelvis that are greater than 2 cm do not require pelvic or periaortic lymph node biopsies unless a clinically enlarged lymph node.
