There is a mass in the scrotum-what does it mean?: Evaluation of the scrotal mass.

Similar to the experience of finding a lump upon physical examination of the breast, the detection of an intrascrotal mass is often a frightening experience for both the patient and his physician. Ultrasound is a nearly ideal modality for evaluation of the scrotum. This manuscript will review the sonographic assessment of the common pathologic and normal conditions that may present as a mass within the scrotum, including discussion of intratesticular and extratesticular etiologies.
