THE IMPACT OF PERCUTANEOUS GUIDED HEPATIC BIOPSY FORTE THE DIAGNOSIS OF PRESUMED BENIGN LIVER-TUMORS

The purpose of this study was to assess the accuracy of guided hepatic biopsy (GHB) and imaging techniques for presumed benign liver rumours and to determine their impact on surgical treatment. The study was ca rried out retrospectively in a surgical series of 15 consecutive patie nts with presumed benign liver tumours. The final diagnosis was 8 case s of focal nodular hyperplasia (FNH), 6 hepatic adenomas (HA) and one association FNH-HA. No morbidity was related to guided hepatic biopsy. All FNH detected on radiologic imaging or pathological examination of the biopsy specimen were true positive diagnoses. This study demonstr ates that combined results of imaging techniques and percutaneous GHB could correctly diagnose three quaters of FNH before surgery. GHB is a lso useful when MRT imaging is indeterminate allowing a conservative a pproach for undiagnosed FNH.
