[Sonographic imaging of soft tissue tumors].

In the course of this study 651 patients with morphologically confirmed soft tissue tumors of different localizations underwent gray-scale sonography, Doppler sonography and energetic Doppler carting. Hitachi HI Vision 900, Logiq-400, Aloka-650, Aloka-2000 scanners wih 5-13 MHz sensors were used. Lipomas, fibrolipomas, benign angioneoplasms and some of the desmoids were shown to have a characteristic sonographical picture. The potential sonographic symptom complexes were determined. Among the malignant tumors the distinct sonographic features were observed in liposarcoma and peripheral nerve sheath tumors. The other soft tissue sarcomas have no characteristic sonographic pattern. In this cases the differential diagnosis could be assisted by clinical signs and medical history analysis.
