Abstract
The sonographic appearance of epidermal inclusion cysts varies in accordance with the contents of the cyst, ranging from an anechoic lesion to a hyperechoic solid appearing mass. Supernumerary testes are an uncommon congenital abnormality, in which more than two testes are present. We present a rare case of a ruptured scrotal extratesticular epidermal inclusion cyst, which had the sonographic appearance of a supernumerary testicle with torsion.
