Evaluation of vascular patterns of cervical lymph nodes with power Doppler sonography.

Power Doppler sonography was used to evaluate 105 benign and malignant cervical lymph nodes in 60 patients. Three main vascular patterns were identified: type I (single vascular pole), type II (hypertrophic vascular pole), and type III (mainly peripheral vascularity). The first one was related to chronic inflammation (sensitivity 85%, specificity 90%); the second and third were related, to a lesser extent, to acute inflammation and neoplasm (sensitivity 68% and 55%, specificity 47% and 91%, respectively). The authors conclude that the sensitivity and specificity of power Doppler sonography cannot compete with those of fine-needle aspiration biopsy in the diagnosis of adenopathy.
