Abstract
Three hundred and thirty-six B-mode ultrasound examinations of the retroperitoneal region were performed on 179 patients with Hodgkin''s disease or non-Hodgkin''s lymphoma. Histological confirmation was available in 56 patients. Ultrasonography was correct in predicting retroperitoneal periaortic lymph node involvement in 87.5% of cases. Node size was correctly predicted 98.2% of the time, and nodes 2 cm or larger in diameter were detectable. Ultrasound was more accurate than physical examination, and as accurate as 67Ga imaging and lymphography in disease detection. The combination of ultrasound and Ga imaging gave the best accuracy of detection (97%).
