Figure 2. (a) Longitudinal image of the left testis demonstrating a focal area of low reflectivity (between cursors) with internal echoes, and widespread microlithiasis (arrows). (b) Colour Doppler image, on optimal low flow sensitivity, of the lesion demonstrating no internal colour Doppler signal within the low reflective areas. Internal echoes are again demonstrated. (c) At 4 weeks there has been reduction in size of the lesion (arrow), with no internal colour Doppler signal present. (d) 1 year later, there is no abnormality present in the left testis at the site of the previous lesion; microlithiasis remains.
