Multipametric Ultrasonographic Diagnostics of Extraorganic Soft Tissue Tumors Containing Adipose Tissue

Abstract

Purpose: To develop algorithms for echographic differential diagnosis of soft tissue tumors containing fat tissue, the data of the complex examination were analyzed, including using various ultrasound techniques, including different types of dopplerography and compression elastography.Material and methods: Echographic studies of verified histologically 221 (63 %) lipomas, 87 (24.8 %) liposarcoma, 43 (12.2 %) hemangioma and lymphangosis of different superficial localizations were performed on Hitachi HI Vision 900, Logiq-400, Aloka-650, Aloka-2000 with 5-13 MHz sensors.Results: It has been established that ultrasonic elastography in a number of clinical situations can be a significant addition in the differentiation of lipomas and highly differentiated liposarcoma, as well as in determining the boundaries of diffuse tumors from adipose tissue. Diagnostic algorithms for differentiating tumors have been proposed.Conclusions: Differential diagnosis of fat-containing soft tissue formations is very complex and requires a multiparametric approach in ultrasound diagnostics.
