question: My dad (59) yrs old did a sonogram on his testicle and was found 3 small dark spot. Could it be cancer? There are the sonogram finding: There are 3 irregularly bordered small hypoechoic defects present in the left testicle. The largest is 0.3 cm, towards the mid- lower pole. The other two are upper pole. On image submitted there was no Doppler suggestion of vascularity within these lesions, on repeat real-time reviews, there appears to be internal vascular to the lesions. There is a small anechoic defect within the midsole of he left testicle which real time color dropper indicated was a vessel.
