Figure 1. (a) Longitudinal image of the left testis demonstrating two low reflective intratesticular lesions (arrows) with evidence of internal areas of high reflectivity. (b) Colour Doppler image, on optimal low flow sensitivity, of the two lesions demonstrating no internal colour Doppler signal within the low reflective areas. (c) At the 1 month follow-up examination only a single low reflective lesion remains (arrow) with central echoes present. No internal colour Doppler signal was present in the lesion. (d) At 3 months the lesion has regressed further (arrow) appearing as an ill-defined area of low reflectivity with some internal echoes.
