What does an abnormal lymph node look like on ultrasound?

Sonographic features that help to identify abnormal nodes include shape (round), absent hilus, intranodal necrosis, reticulation, calcification, matting, soft-tissue edema, and peripheral vascularity.

How can you tell the difference between benign and malignant lymph nodes?

Benign nodes have been found to have a long-axis diameter at least 2 times the short-axis diameter, with a shape index of less than 0.5, corresponding to an oval shape. Malignant nodes have been found to have a shape index of greater than 0.5, corresponding to a more rounded shape.

Can you have a benign lymphoma?

Benign lymphoma is a tumor that develops from lymphocytes (a type of white blood cell that fights infection). Benign lymphoma, also called pseudolymphoma or benign lymphoid hyperplasia, is a rare noncancerous (benign) tumor made up of lymphocytes.
