Angle measurement of the papillary projection in unilocular-solid adnexal cysts as predictor of malignancy: A three-dimensional ultrasound study

ABSTRACT: Aim and objective: To analyze the value of the angle between the papillary projection and the cyst´s wall for differentiating between benign and malignant adnexal masses using three-dimensional ultrasound. Materials and methods: Retrospective study between January 2003 and December 2012 including a series of non-consecutive patients diagnosed as having a unilocular-solid mass in ultrasound. Definitive diagnosis was based on a histological result obtained after surgical removal or ultrasonographic follow-up until the disappearance of the mass. In a 3D volume, the angles formed by the solid component and the cyst’s wall in both lateral borders were measured in the three planes, obtaining six different angles. The variables analyzed were an average angle, widest angle, narrowest angle, the difference between the widest and narrowest angle, number of obtuse (>90°), and acute (<90°) angles. Results: Eighty-one patients were included. The patient’s mean age was 44.2 years. Twenty-four (29.6%) of them were postmenopausal and 57 (70.4%) were premenopausal. The mean average angle, widest angle, narrowest angle, the difference between the widest and narrowest angle, number of obtuse and acute angles in benign masses were 81.5°, 105.3°, 58°, 47.3°, 2.3, and 3.7, respectively. These figures in malignant masses were 75.7°, 103.7°, 49.1°, 54.6, 1°, 1.8, and 4.2, respectively. We did not find statistical significance in any comparison. Conclusion: Measurement of the angles between the solid component and the cyst’s wall in unilocular-solid adnexal masses with only one papillary projection is not useful as a predictor of malignancy.
