ABSTRACT

An extratesticular scrotal epidermal cyst is a very rare condition and few cases of extratesticular scrotal epidermal cyst with radiologic findings have been reported. Therefore, we report here on a rare case with ultrasonographic and MRI findings. A 70-year-old male patient was admitted with a palpable mass in the left scrotum. A well-defined heterogeneous hypoechoic mass with scattered echogenic reflectors in the scrotum was identified on ultrasonography. The cystic mass showed high signal intensity on T2-weighted images, low signal intensity on T1-weighted images, and diffusion restriction on diffusion weighted images.
