Abstract
Solid lesions in different localisations of the pelvis were biopsied with a large-bore Tru-Cut cannula (G 14) in 88 patients under computed tomographic guidance. Special techniques for safe access to pelvic lesions are described. Indications for biopsy were suspected extraluminal tumour recurrence (n = 49), masses outside the pelvic organs in the absence of a known pelvic primary (n = 21) and in the presence of a known pelvic primary (n = 10). In 8 cases, lesions situated within pelvic organs were punctured. Without any repeat biopsy, accuracy reached 96.6%, sensitivity was 95.2% and specificity was 100%. In comparison to the results of FNA reported in the literature diagnostic accuracy can be improved upon by using large-bore biopsy. No complications occurred.
