Nghiên cứu đặc điểm hình ảnh và giá trị siêu âm trong chẩn đoán hạch cổ ác tính

SUMMARY

Background: The purpose of the study was to evaluate the characters and efficacy of B Mode and color Doppler ultrasound (CDUS) in diagnosis malignant cervical lymph nodes.

Materials and Methods: In this cross-sectional prospective study, during a period of 12 months, performed on 85 patients including two groups: group I includes 63 patients with cervical lymphadenopathy with suspected lymph nodes on US and group II includes 22 patients with clinically suspected lymph nodes (not have any suspicious characteristics in US) were prospectively evaluated with B-mode and CDUS. Statistical analysis was carried out with histopathological or cytological diagnosis as gold standard.

Results: We conducted ultrasound in 85 patients,. To compare with the pathology results of the disease, there are 56 metastatic lymph nodes, 04 lymphoma nodes, 01 plasmocyoma lymph node, 18 nonspecific inflammatory lymph nodes, 01 purulent lymph node and 05 granulomatous lymph nodes due to tuberculosis. The sensitivity, specificity, the accuracy of 2D ultrasound method combined with Dopper ultrasound are 95.08%, 79,2 %, 92%, 86% và 90,6%.

Conclusions: Within the limitations of this study, B-mode and CDUS evaluations were found to be highly significant with a high sensitivity and specificity. B-mode and CDUS examinations provide a prospect to reduce the need for biopsy/fine needle aspiration cytology in reactive nodes.
