[False-positive findings in screening for abdominal aortic aneurysm].
The incidence of false-positive screening results in connection with ultrasound scans (US) for abdominal aortic aneurysms (AAA) is unknown, but it is presumably a rare occurrence. The estimated predictive values of both false and true screening results are high because abdominal US describes the aortic diameter with a high precision. We describe a false-positive finding in a 66-year-old male. US abdominal screening led to a suspected 8.3 cm AAA. Consequently, a computed tomography was performed showing an AAA of normal proportions and a big bladder diverticulum in front of the aorta abdominalis.
