Only 3 cysts were malignant (one of them borderline). All three patients were postmenopausal. The mean diameter of the malignant cysts were 7, 11 and 18 cm, respectively. 82 sonographically simple cysts were histologically benign. We found 27 cysts associated with chronic pelvic sepsis (hydrosalpinx and pseudocysts), 22 were benign cystadenomas and 10 were endometriotic.\nSimilar content being viewed by others\nReferences\nAndolf E, Jörgenson C (1989) Cystic lesions in elderly women, diagnosed by ultrasound.
