Epidermoid cysts of the testis are rare benign lesions, without malignant potential, that can be managed conservatively with cyst enucleation and testis‐sparing surgery. Bilateral epidermoid cysts in the testes have been reported very infrequently. We report the sonographic and MRI findings in a patient who presented with a palpable nodule in only 1 testis, but in whom sonography showed bilateral lesions. On sonography, the cysts had an internal “onion‐ring” structure; color Doppler signals were absent. On MRI, the cysts had a laminated appearance, with alternating low‐ and high‐signal‐intensity areas on T2‐weighted images. These imaging findings and the negative results of laboratory tests for tumor markers suggested the correct diagnosis, and testis‐sparing surgery could be performed. © 2004 Wiley Periodicals, Inc.
