ABSTRACT
Answer: (b) Ultrasound is very accurate in distinguishing testicular from extrates ticular lesions. While ultrasound can detect cystic changes which occur more commonly in benign lesions, it cannot reliably make the distinction between benign and malignant tumors. It can also be misleading with regard to the feasibility of testis-sparing surgery as even large lesions may be enucleated leaving a reasonable amount of normal parenchyma. Ultrasound is not routinely used for staging or determining the vascularity of a lesion.
