Scrotal MRI of patient with simple testicular epidermoid cyst, 1.5 Tesla MRI, surface coil. a T1 weighted imaging showing cyst with lower signal intensity than testicular parenchyma. b. T2-weighted imaging: typical bull-eye appearance of epidermoid cyst. Note the high signal intensity within cyst core. c and d. T1-weighted imaging with application of gadolinium-based contrast material. Note signal enhancement in testicular parenchyma but not in the cyst core highlighting the avascular area within the cyst
