Sonography of scrotal abnormalities in adults: an update.

The purpose of this pictorial review is both to demonstrate newly described conditions such as whirlpool sign, fibrosis, benign testicular lobulation, and effect of hydrocele on the testis and to scrutinize usual and unusual scrotal abnormalities to bring the reader up to date. The use of ultrasonography will give the correct diagnosis in most conditions providing that it is used appropriately. Familiarity with the ultrasonography features of both common and newly described entities is important for the management of scrotal abnormalities.
