Abstract:
Testicular epidermoid cyst (TEC) is an uncommon benign testicular lesion that can be successfully cured via lesion enucleation and at the same time preserving patient's fertility. Doppler ultrasound (US), contrast-enhanced MRI and tumor markers are helpful in the diagnosis of TEC if the lesion does not show typical characteristics such as onion skin and target appearance. Herein, we report a case of TEC without typical structural characteristics but heterogeneously mixed echogenic content in US examination, no internal vascularity in the color Doppler study and lack of contrast enhancement in MRI images. These additional findings are helpful for diagnosing TEC.
