Imaging in testicular epidermoid cysts.

ABSTRACT

OBJECTIVE: To evaluate the utility of findings on ultrasound and magnetic resonance imaging (MRI) for the preoperative diagnosis of testicular epidermoid cysts (TEC). METHODS: The medical records of five patients treated for TEC at our institution between July 2010 and May 2017 were retrospectively reviewed. RESULTS: Imaging revealed a target or onion skin appearance on ultrasonography and MRI. Pathological examinations showed "bread slag-like" materials within the TEC. Lesions failed to demonstrate enhancement after Gd-DTPA injection. CONCLUSION: In the cases of TEC in the current study, accurate diagnosis ensured enucleation of the testicular cyst was performed rather than testicular resection.
