Benign versus Malignant Lymphadenopathy: The Usefulness of Color Doppler Sonography

Purpose : To evaluate the vascular pattern of lymph nodes, and the usefulness of color Doppler sonogaphy in differentiating benign from malignant superficial lymphadenopathy. Materials and Methods : Twenty-six patients were pathologically and clinically confirmed to be suffering from benign reactive lymphadenitis and tuberculosis(n=16) or lymphoma and malignant lymphadenitis (n=10). Lymph node shape was assessed by the ratio of longitudinal diameter to transverse diameter(L/T), and patients were thus assigned to one of two groups : , or L/T, and 3 L/T
