Background
Testicular tumors are the most common malignancy in men ages 15–34 years. It is essential for radiologists to understand the various sonographic appearances of testicular neoplasms, and how to differentiate malignant masses from benign mimics. Understanding common clinical presentations and lab abnormalities will assist the radiologist in consulting with the treatment team to make the diagnosis.

Educational Goals / Teaching Points
Educational goals for this presentation include providing a basic framework for organizing the various testicular masses and their sonographic findings. The viewer will be able to recognize common clinical presentations and lab values associated with various tumors and how to recognize important tumor mimics. Additionally, the viewer will understand important next steps in management of testicular masses.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will review the sonographic appearance of various testicular masses in the form of a case-based review, including several quiz cases. These cases will include malignant germ cell tumors (seminomas and non-seminomatous), as well as non-germ cell tumors, including Sertoli and Leydig cell tumors, and various hematopoietic and secondary tumors. In addition, common clinical presentations, lab values, and important mimics will be presented (e.g., intratesticular abscess, trauma, and sarcoidosis).

Conclusion
Understanding common presentations, sonographic features, and lab abnormalities associated with testicular tumors will aid in diagnosis and management. Furthermore, understanding benign mimics will prevent unnecessary treatment and surgery.
