High‐resolution ultrasonography in the diagnosis of scrotal pathology: I. Normal scrotum and benign disease

Ultrasonography is a readily accessible imaging modality. It is relatively inexpensive, is noninvasive, and requires no ionizing radiation or previous preparation. For these reasons, ultrasonography is the examination of choice in the study of the scrotum and its contents. We present a review of the pathology of the scrotum and its contents. For that, we cite multiple sources of the current medical literature and illustrate them with cases performed at the University of California Davis Medical Center during the last 2.5 years. Due to the extent of the pathology in consideration, we have divided it in two parts. This article deals with normal ultrasonography anatomy, technique, epididymal and testicular cysts, scrotal calcifications, acute and chronic inflammatory disease, testicular torsion, scrotal trauma, varicocele, undescended testis, and miscellaneous conditions.
