[Ultrasonic diagnosis, computed tomography and lymphography of retroperitoneal lymphomas--re-evaluation of lymphography].

Regarding the present results and the review of literature, we are of the opinion that negative attitude towards lymphography is not justified. In diagnostic procedure, priority is given to sonography and computed tomography because of their non-invasiveness. Lymphography is indispensable in all cases where sonography or computed tomography show negative findings and where the therapy planning depends on evidence or exclusion of retroperitoneal lymphomas. In general the combination of both computed tomography and lymphography is the most sensitive and consequently, the safest method in the diagnosis of retroperitoneal lymphomas.
