Abstract
OBJECTIVE. The objective of our study was to determine the value of color Doppler imaging as an adjunct to gray-scale sonography to reveal the intra- or extraparotid origin of jugulodigastric nodules of uncertain location. SUBJECTS AND METHODS. Forty nodules in the jugulodigastric area from 38 patients were imaged with gray-scale, color, and power Doppler sonography. Nodules receiving vessels from salivary glands were assumed to be intraglandular; those accepting vessels from paraparotid spaces were considered to arise from outside the gland. Imaging results were correlated with biopsy and surgical findings. RESULTS. In 38 of 40 cases, color and power Doppler sonography displayed discrete feeding arteries leading to the nodules: 25 nodules had one supplying artery, nine received two arteries, and four had three or more arteries. Intraparotid nodules received vessels from the gland in 20 cases. In two cases, the source of vessels was indeterminate. In two malignant tumors, multiple arteries derived from both the parotid and the neck spaces. All 14 extraparotid nodules received the arterial supply from paraparotid spaces. Color Doppler sonography enabled prediction of the intraglandular location of the nodules in 91% of cases and the extraglandular location in 87.5% of cases. The correct diagnosis was achieved in 34 of 40 nodules, with a global accuracy of 85%. CONCLUSION. Color Doppler sonography can help to assess the intra- or extraparotid location of jugulodigastric nodules. In practice, this technique can support the diagnosis when gray-scale sonography raises doubts about the origin of a jugulodigastric nodule.
