  • Title: Fine needle aspiration of the liver.
    Author: Pinto MM, Avila NA, Heller CI, Criscuolo EM.
    Journal: Acta Cytol; 1988; 32(1):15-21. PubMed ID: 2827416.
    Abstract:
    A total of 81 transhepatic fine needle aspiration (FNA) biopsies were performed on 78 patients to rule out focal or diffuse neoplastic disease; 87.6% were performed with ultrasound guidance, 6.1% with CT guidance, 3.7% intraoperatively and 1 using fluoroscopy during percutaneous transhepatic cholangiography. Smears of the aspirated samples were cytologically evaluated with clinical and radiologic correlation; in addition, histologic examination of cell blocks was performed in 46% of the cases, ultrastructural examination in 34% of the cases and peroxidase-antiperoxidase staining in 3 cases. Ultrastructural definition of the type of malignancy was possible in 24 cases (29%). Minor complications in two patients were pain and tenderness at the puncture site. The sensitivity for malignancy was 91%, the specificity was 100%, the predictive value of positive results was 100%, and the predictive value of negative results was 73%. This series demonstrates that FNA biopsy with ultrasound guidance can provide an accurate diagnosis of malignancy and may preempt a lengthy workup in the search for a primary tumor.
