(b) Color Doppler US image shows absence of vascularization. (c) Strain elastography image shows a medium-to-hard (encoded blue–green) focal lesion. (d) Early and (e) late phases CEUS show the lesion with nonenhancement. (f) The lesion decreases in size significantly one month later. Three months later, the lesion disappears completely. Finally, it is confirmed to be a testicular hematoma. The arrows indicate testicular hematoma. US: ultrasound; CEUS: contrast-enhanced US.
