Objective. The purpose of this series was to describe the sonographic features of intratesticular epidermoid cysts with clinicopathologic correlation. Methods. A retrospective review of the sonographic features of all intratesticular epidermoid cysts within the radiologic pathology archive of the Armed Forces Institute of Pathology with correlation with clinical, surgical, and pathologic data was performed. On sonograms, intratesticular epidermoid cysts were evaluated for shape, borders, and the presence of characteristic features, including alternating hypoechoic and hyperechoic rings, mural calcifications, and echogenic central core. Color Doppler imaging was evaluated for the presence of internal flow. Results. Of 21 cysts seen in 20 male patients (mean age, 24 years; range, 11–52 years), the most common finding was mural calcifications, which were seen in 18 lesions (86%). Concentric rings of alternating echogenicity were shown in 13 lesions (62%), and 7 cysts (33%) had an echogenic central core. No cysts showed internal vascularity. Conclusions. Testicular epidermoid cysts are uncommon solid‐appearing testicular masses that usually present as palpable masses and are benign. Knowledge of the sonographic and pathologic features may help differentiate these lesions from malignancy and possibly prevent unnecessary orchiectomy.
