Abstract

Fine-needle aspiration (FNA) of the pelvis and retroperitoneum (excluding the pancreas, kidney, and adrenal masses) has not achieved its full potential as a diagnostic modality. We reviewed 68 percutaneous, radiologically guided FNAs from these locations to assess the clinical utility and complication rate of this procedure. Satisfactory' material was obtained in 66 cases (97.1%), of which 37 were deemed positive (55%), 3 suspicious (4%), 4 atypical (6%), and 22 negative (32%) for malignancy; two cases (3%) were unsatisfactory. Compared to biopsy (36 patients) and clinical information, the sensitivity and specificity of FNA for malignancy were 90.2% and 100%, respectively, yielding a positive predictive value of 100% and a negative predictive value of 86.6%. The four false-negative cases (5.9%) were due to sampling error. One patient had a minor complication (hematoma) from the procedure. We conclude that FNA is the procedure of choice for detecting most malignancies in these two locations.
