Simple testicular cysts are usually nonpalpable and thus are detected incidentally.
Testicular cysts require no treatment when discovered.
On US, testicular cysts are usually well-defined and anechoic with enhanced through transmission and an imperceptible wall.
At MR imaging, the lesion follows the signal characteristics of fluid with all pulse sequences.
Careful inspection is warranted to differentiate these from cystic testicular neoplasms, such as cystic teratoma.
Contrast-enhanced MR imaging aids in this diagnosis by demonstrating lack of solid enhancement in these lesions.
