Abstract
Pathological lesions within the scrotum are relatively rare in imaging except for ultrasonography. The diseases presented in the paper are usually found in men at the age of 15–45, i.e. men of reproductive age, and therefore they are worth attention. Scrotal ultrasound in infertile individuals should be conducted on a routine basis owing to the fact that pathological scrotal lesions are frequently detected in this population. Malignant testicular cancers are the most common neoplasms in men at the age of 20–40. Ultrasound imaging is the method of choice characterized by the sensitivity of nearly 100% in the differentiation between intratesticular and extratesticular lesions. In the case of doubtful lesions that are not classified for intra-operative verification, nuclear magnetic resonance is applied. Computed tomography, however, is performed to monitor the progression of a neoplastic disease, in pelvic trauma with scrotal injury as well as in rare cases of scrotal hernias involving the ureters or a fragment of the urinary bladder.
