Presence or absence of normal ovarian tissue adjacent to adnexal mass: a discriminative sonographic sign to suspect malignancy.

摘要

It has been claimed that the presence of normal ovarian tissue adjacent to an adnexal mass, ovarian crescent sign (OCS) excludes the likelihood of a malignant lesion. And it is considered to be a reliable and simple sonographic marker in preoperative evaluation.We studied 60 women attending gynecology service with adnexal mass requiring surgery. Ultrasound scanning was done by a single gynecologist who was not aware of the clinical details. Criteria suggested by Hillaby et al were used for identifying OCS. Its presence or absence was correlated with the histopathology examination report of the tumor obtained at surgery.
