High-resolution US is the imaging modality of choice in the evaluation of the acute scrotum. Knowledge of the normal appearance of the testis and scrotal contents and familiarity with the many pathologic conditions that may affect the scrotum are essential for expedient and accurate diagnosis of scrotal pathology. Proper US technique is critical, especially in the evaluation of torsion and testicular rupture. Some conditions have overlapping sonographic features, and follow-up to resolution is required to exclude underlying malignancy.
