ABSTRACT
Ultrasound is the imaging modality of choice to evaluate the scrotum because of its high resolution, Doppler capabilities, availability, and lack of ionizing radiation. Acute urologic emergencies diagnosed with ultrasound include testicular torsion, testicular rupture, and Fournier gangrene. The radiologist's knowledge of sonographic features of vascular, infectious, traumatic, and benign and malignant processes that occur in the scrotum coupled with the patient's presenting symptoms, age, and physical examination allows for the correct diagnosis of a wide spectrum of scrotal pathology.

Soft tissue masses and fluid collections are frequently encountered in sonographic practice, either as principal indication for diagnostic examination or as an incidental finding during an examination performed for other indications. Sonography is a good first-line imaging modality for evaluation of superficial masses and fluid collections, but requires meticulous attention to technique to avoid diagnostic pitfalls. Although many superficial masses are diagnosed with ultrasound, there are several potential diagnostic challenges, including differentiating hematomas from sarcomas. This article provides an image-rich review of the sonographic features of common soft tissue masses, with emphasis on practical tips to accurately recognize important pathology.
