Abstract
Preliminary and reviewed statements describing results from abdominal CT and US were compared with surgical findings and with the report from the histopathological investigation of extirpated retroperitoneal tissue. No false positive diagnoses of retroperitoneal metastases were made by CT investigation, while US made one false positive but revealed metastases in one patient overlooked by CT. The overall accuracies (correct answers/all patients) were 81% with CT and 80% with US (31 and 21 patients in Group 1 respectively). Surgical exploration alone was no more sensitive than either of the two other methods. CT and US are highly reliable when positive but the risks of obtaining false negative results are considerable.
