    Abstract:
    This study was undertaken to verify the role of fine-needle aspiration (FNA) followed by cytologic examination as a possible alternative to surgery in case of cystic pelvic masses. From January 1988 to March 1989, 204 patients with a proven cystic pelvic mass underwent FNA under sonographic guidance. In 20 cases the aspiration was performed transvaginally. Thirty-six patients were postmenopausal. In all cases the aspirated fluid was collected for cytologic evaluation. Other than one case of persistent hematuria, no complications occurred. The overall recurrence rate, verified 3 months from FNA, was 65%. Fifty-two per cent of patients developed a new cyst after a complete aspiration. Fifty-three patients underwent a laparotomy, allowing a comparison between cytologic and histologic patterns. The sensitivity of cytologic examination of aspirated fluids was 40% (3 of 5 malignancies were missed) and the specificity was 100% (no false positives were observed). We conclude that FNA might be proposed in young women with a unilocular ovarian cyst to avoid a surgical procedure. In postmenopausal women with a unilocular cystic mass 5 cm or less, FNA may be considered as an important step in the diagnosis. In all instances the ultrasonographic appearance of the cyst (echo texture and regularity of wall) and the characteristics of aspirated fluid are the most important findings. When the aspirated fluid contains mucus or blood, or when a complex mass is present, exploratory laparotomy or a laparoscopy is recommended.
