Abstract
UNLABELLED: Since focal lesions of the spleen are rare (0.2%), there is little data concerning color Doppler images of focal lesions of the spleen. OBJECTIVE: The aim of this study is to describe the color Doppler images of 98 etiologically proved focal spleen lesions. METHODS: In about 110,000 consecutive abdominal ultrasound examinations, which included the spleen, 600 patients with focal lesions of the spleen were identified. In 98 of these patients a color Doppler scan of the lesion was performed and documented. These scans were analysed retrospectively and classified as avascular, hypovascular, isovascular, hypervascular and arterio-venous "high flow", using the surrounding spleen tissue as an in vivo reference. RESULTS: In color Doppler sonography (CDS) 68.4% (n=67) of the focal spleen lesions showed no flow. 15.3% (n=15) appeared hypovascular, 8.2% (n=8) isovascular, 5.1% (n=5) hypervascular, and in 3.1% (n=3) an arterio-venous "high flow"-pattern was found. CONCLUSIONS: In CDS about two thirds (68%) of focal spleen lesions appear to be avascular. Except from diagnosis of intra-splenic pseudo-aneurysm, the practical utility of CDS in diagnosing focal spleen lesions has to be estimated as low.
