“…Those masses were commonly found on daily pelvic sonographic examinations and were complex due to the changes in menstrual cycles, disease durations, and other pelvic diseases. Sonographic characteristics of these masses were abnormal and various, as the same sonograms may have shown different diseases, and different sonograms may have shown the same disease 3 , 20 , 21 . Differential diagnosis between benign and malignant masses was then needed to treat patients accordingly.…”

Objectives The purpose of this study was to evaluate the efficacy of the combination of 2‐dimensional (2D) and 3‐dimensional (3D) contrast‐enhanced sonography in discriminating between benign and malignant small adnexal masses. Methods Selected patients were evaluated with both 2D and 3D contrast‐enhanced sonography after conventional sonography before undergoing any surgery. Time‐intensity curves for 2D contrast‐enhanced sonography were constructed by using contrast‐enhanced sonographic software. A vascular perfusion characteristic analysis was achieved by 2D and 3D contrast‐enhanced sonography. Results were finally verified by surgery. Results Forty‐seven cases of benign and 10 cases of malignant small adnexal masses were discovered. Significant differences in perfusion patterns, time‐intensity curve shapes for 2D contrast‐enhanced sonography, grayscale contrast‐enhanced sonography, and blood flow imaging on 3D contrast‐enhanced sonography were observed between benign and malignant masses (P< .05). Two‐dimensional contrast‐enhanced sonography, 3D contrast‐enhanced sonography, parallel combination of 2D and 3D contrast‐enhanced sonography, and serial combination of 2D and 3D contrast‐enhanced sonography all reached diagnostic sensitivity of 100% for discriminating benign from malignant masses, whereas specificity values were 61.7%, 63.8%, 68.1%, and 57.4%, respectively. Areas under the receiver operating characteristic curves were 0.809, 0.819, 0.840, and 0.787. Conclusions Two‐dimensional contrast‐enhanced sonography is of high value in distinguishing malignant from benign small adnexal masses; 3D contrast‐enhanced sonography provides richer and more useful information for evaluation of these masses. Diagnostic sensitivity of 100% can be achieved when using a serial combination of 2D and 3D contrast‐enhanced sonography, although specificity needs further improvement.

“…Venous flow velocity was found significantly higher in malignant than in benign masses (18.1 cm/sec vs. 8.9 cm/sec, P = 0.0006). Sensitivity, specificity, and positive and negative predictive value for the combination of both arterial and venous Doppler were 88%, 91%, 79%, and 95%, respectively 32 …”

“…Sensitivity, specificity, and positive and negative predictive value for the combination of both arterial and venous Doppler were 88%, 91%, 79%, and 95%, respectively. 32 More recently 3D power Doppler depicts the morphology of tumor vessels and with the use of contrast-enhanced imaging, it reaches sensitivity and specificity values of 100% and 93.3%, respectively. The positive and negative predictive value of this method was found 85.7% and 100%, respectively reaching diagnostic accuracy of 95.6% in discriminating benign from malignant adnexal lesions.…”

In the past few years the contribution of operative laparoscopy in all fields of gynecological surgery has been revolutionary. Nowadays laparoscopic management of adnexal masses is the most frequently performed laparoscopic intervention. Laparoscopy in comparison to laparotomy has the advantages of lower morbidity, shorter length of hospital stay, decreased postoperative pain, lesser de novo adhesion formation, better cosmetic results, faster recovery, and reduced overall cost of care. However, careful preoperative evaluation is important for the appropriate and successful use of laparoscopy for removal of adnexal masses and the advantages of the laparoscopic approach should, in no way, compromise the clinical outcome in women with malignancy. Patient's age, history, findings of physical examination, and the results of serum markers in combination with the imaging assessment, such as Doppler sonography, CT, or MRI, should be considered to reach the diagnosis preoperatively. However, only pathology of the adnexal mass can provide the definitive diagnosis. The specific characteristics of the adnexal masses in childhood, adolescent, reproductive, and postmenopausal age represent the essential parameters that will determine the therapeutic strategy to be followed. Furthermore, the clinician has to determine whether an adnexal mass requires surgery or expectant management as well as to estimate the possibility of malignancy.
