[Correlation of cytologic and pathohistologic findings in ultrasonically-guided thin-needle biopsy of abdominal and retroperitoneal organs].

The ultrasonically guided fine needle biopsy is cheap, very sensitive and specific method for the diagnosis of nonpalpable deep-seated lesions. During 1992 in the institute of Radiology of Military Medical Academy in Belgrade 87 biopsies of abdominal and 81 biopsies of retroperitoneal organs were performed for the cytological and histopathologic analysis. Deficient material was obtained in 15.4% of the cases. A good correlation between cytologic and histopathologic findings was observed, with diagnostic concordance in 90.8%. In 9 cases with falsely positive cytological diagnosis at the first examination, the diagnosis of malignancy was later confirmed by other diagnosis procedures. Diagnostic difficulties and the significance of adequate biopsy were particularly stressed.
