Ultrasound (US) is the most widely available method of diagnostic imaging for the evaluation and characterization of gonadal lesions and is usually the method of choice because of its high accuracy, low cost, and wide availability. Today's high-resolution images allow for a confident diagnosis of many scrotal and adnexal lesions, with high sensitivity and specificity. Magnetic Resonance Imaging (MRI) is reliable in the detection of gonadal lesions in males, allowing the differentiation into testicular or nontesticular lesions, and their characterization. It is also an accurate and cost-effective diagnostic adjunct in those patients with solid scrotal lesions for whom the findings of clinical and US evaluations are inconclusive. In females, MRI is recommended as a second-line investigation for the characterization of complex adnexal masses that are indeterminate on US. In this chapter gonadal pathologies related with the steroidogenic and gametogenic function of the testes and ovaries will be discussed. The main imaging features of benign and malignant lesions will be presented.

Abstract

Ultrasound (US) is the most widely available method of diagnostic imaging for the evaluation and characterization of gonadal lesions and is usually the method of choice because of its high accuracy, low cost, and wide availability. Today's high-resolution images allow for a confident diagnosis of many scrotal and adnexal lesions, with high sensitivity and specificity. Magnetic Resonance Imaging (MRI) is reliable in the detection of gonadal lesions in males, allowing the differentiation into testicular or nontesticular lesions, and their characterization. It is also an accurate and cost-effective diagnostic adjunct in those patients with solid scrotal lesions for whom the findings of clinical and US evaluations are inconclusive. In females, MRI is recommended as a second-line investigation for the characterization of complex adnexal masses that are indeterminate on US. In this chapter gonadal pathologies related with the steroidogenic and gametogenic function of the testes and ovaries will be discussed. The main imaging features of benign and malignant lesions will be presented.
