[Potential for ultrasonic diagnosis in determining the nature of a bulky lesion of the liver].
Ultrasound investigation (USI) of the liver was performed in 6570 patients, focal lesions were detected in 80 (1.2%). Of them 53 patients (66.2%) had a benign process, 27 (33.8%)--a malignant process. Four variants of focal pathology with its specific nature were singled out on the basis of analysis of the echo structure. Anechogenic foci reflected a cystic process, foci of mixed echo density--malignant lesions (a metastasis, liver cancer). The determination of the nature of echo-dense and low echogenic foci is the most complex problem of USI. In most cases echo-dense foci reflected benign liver tumors (7:1). USI in 56.3% of patients permitted the recognition of the nature of a sizable liver tumor without resorting to other radiation-methods; in another one-third of patients--during dynamic observation.
