About This Book
There are many possible causes of pelvic pain in a non-pregnant female patient, and it has been estimated to be responsible for nearly 40% of all visits by female patients to a family doctor and 10% of all referrals to specialist gynecologists. However, the topic of how to investigate and diagnose has been surprisingly neglected in print. This important and much-needed text from internationally respected experts shows how important ultrasound can be as a tool for physicians caring for women's health.

Chapter 1
Benign Adnexal Masses and Adnexal Torsion
Juan Luis Alcázar
Introduction
Adnexal masses are relatively common in women. Most of these tumors are benign.1 Histologically, the ovary may be the origin of many different types of benign tumors and there are tumors arising from the fallopian tube (Table 1.1). Most benign tumors remain asymptomatic but some of them may cause symptoms, such as pelvic/abdominal pain, menstrual disorders, or symptoms related to space-occupying lesions. In fact, adnexal torsion is most frequent in benign tumors than in ovarian cancer.2 Transvaginal ultrasound has been shown as the best imaging technique for assessing adnexal masses,3 especially when performed by an expert examiner.4 In this chapter, we will review the ability of transvaginal ultrasound for discriminating between the most common types of benign lesions arising from de ovary and tube, as well as current management options. We will also address the role of ultrasound in diagnosing and managing adnexal torsion.

Benign Adnexal Masses: Diagnosis and Management
Serous Cystadenoma
Serous cystadenoma constitutes about 25% of all benign epithelial ovarian tumors arising from the ovary; 5% of them are bilateral and most of them appear in the fourth to sixth decades of life.1 The typical ultrasound appearance of serous cystadenomas is a smooth, thin-walled, anechoic, fluid-filled lesion with a mean size of 5–8 cm (Figure 1.1a).5,6 Septations may appear in 14% of the cases and irregular wall or even papillary projections may be present in up to 3% of serous cystadenomas (Figure 1.1b).5 Color score may vary from absent to moderate flow within the cystic wall.
Mucinous Cystadenomas
Mucinous cystadenomas constitute 25% of all benign epithelial ovarian tumors; 10% of them are bilateral and usually appear in the fifth and sixth decades of life.1 The typical ultrasound appearance of mucinous cystadenoma is a multilocular smooth cyst with a mean tumor size of 11 cm (range 3–30 cm) (Figure 1.2).7,8 Color score is usually absent, or scanty and papillary projections may appear in 20% of the cases. Caspi et al. described that the presence of different echogenicity in different locules of the lesion is almost pathognomonic of a mucinous tumor.9
Endometrioma
Endometrioma is addressed in detail in another chapter of the book. But know that the typical ultrasound appearance of endometrioma is a unilocular cyst with ground-glass echogenicity (Figure 1.3).5,6
Cystadenofibroma
Cystadenofibromas are relatively uncomm...
