Case report of a testicular epidermoid cyst and review of its typical sonographic features.

A case of testicular epidermoid cyst, demonstrating multiple characteristic sonographic patterns in a single lesion, is presented with a brief review of the distinctive ultrasound features. It is important to remember that the sonographic patterns describing testicular epidermoids represent the varied amounts and arrangements of keratin of a particular lesion. A given lesion may demonstrate subtle variability or more than one characteristic pattern at any given time. With this in mind, preoperative characterization of testicular epidermoids should allow for increasing utilization of testicular sparring surgery in the management of this benign lesion.
