[Ultrasonically guided aspiration biopsy in the diagnosis of liver tumors].

The paper is concerned with the analysis of the results of sonographically guided biopsy of hepatic tumors which had been carried out in 30 outpatients suffering primary cancer of the liver (3 cases), metastases (16), lymphosarcoma (2), cysts (2), adenoma (2), hemangioma (4) and hydatidiform mole (1 patient). The sensitivity of the method in tumor diagnosis was 89%, specificity--80%. Ultrasonographic features of the liver pathologies were studied versus morphologic type. Indications and technical requirements for ambulatory ultrasonographically guided biopsy of the liver are discussed.
