OBJECTIVE: To determine the value of fine needle aspiration biopsy (FNAB) in comparison to cut needle biopsy (CNB) for the diagnosis of malignancy of focal liver lesions. STUDY DESIGN: A retrospective analysis was conducted on 68 FNAB and 49 CNB procedures performed on 62 patients with focal liver lesions. RESULTS: Cytology permitted a diagnosis of the lesion in 78% of cases. When punctures with insufficient material were excluded (11), the diagnostic accuracy of FNAB was 93%. For the 49 patients who underwent both procedures, FNAB and CNB had the same diagnostic accuracy, 78%, when considered separately and of 88% when considered in combination. Sensitivity, specificity and positive predictive value were similar for the 2 techniques. The negative predictive value was 64% for FNAB and CNB used separately and reached 78% when the 2 techniques were combined. There were no complications during the execution of FNAB and CNB. CONCLUSION: FNAB is an effective and safe method for the diagnosis of focal hepatic lesions, with diagnostic accuracy similar to that of CNB. When the 2 techniques are combined, the accuracy of the diagnosis of malignancy of focal liver lesions increases.
