The evaluation of fine-needle procedures for the diagnosis of focal liver lesions in cirrhosis

摘要: To evaluate the diagnostic accuracy of fine-needle aspiration, biopsy and extranodular fine needle in identifying focal lesions cirrhosis, 100 consecutive ultrasound detected nodules were studied. Seventy-three hepatocellular carcinomas (31 well-differentiated carcinomas), 23 benign (one angioma 22 large regenerative nodules) two metastases. The divided according to maximum diameter as follows: 20 30 mm 33. In four cases there multiple different sizes. Fine intranodular obtained each lesion. sensitivity, specificity procedure evaluated separately by three independent pathologists. Seven aspirations biopsies considered inadequate. highest (96%) was combined analysis aspiration plus biopsy, this superiority confirmed group lesions. showed a lower (48%) than (67%). When together, an 91% found. Intralesional gave 78% and, particularly relevant, 95%. These results indicate that, patients with cirrhosis nodular
