In order to develop further the criterias of the ultrasonographic diagnosis of the lip- and lymphedema, also in the demarcation of the phlebedema, we examined 100 patients in our practice. In addition to the specific “sonomorphology”of the lip- and lymphedema we found a different reaction of the subcutaneous tissue of the lower leg in painful and not painful lipedemas examined with compression-sonography. A more precise demarcation of the cutis from the subcutis was made possible with a new 13 MHz linear probe. The spontaneous painful lipedema shows a thickened subcutis with increased echogenity and is only compressible at 10 to 20 percent, while the not painful lipedema is compressible at about 50 percent. In patients with lymphedema the typical echoless gaps showed no colour coding and were also not compressible. Especially because of the low time needed, the non-invasive method and the lack of radiation the ultrasonographic description, measurement and compression of the subcutaneous tissue of the lower leg is useful for diagnosis, the objective control of therapeutic strategies and the estimation of the clinical symptoms – especially in cases of lipedema – and also for the etiology – especially in cases of lymphedema. The sonography is superior to the clinical examination and should be the second step in diagnosis of all nonsystemic forms of edemas of the legs.
