Ultrasonography was performed after infarction, revealing uneven localized heterogeneous echogenicity with no internal blood flow signal in the upper pole of the left testis, measuring 24 mm * 26 mm (A). The upper part of the left testicle showed an avascular area (B). One week after the infarction, the ultrasound showed that the echogenicity of the upper half of the left testis was reduced, measuring 20 mm * 19 mm (C), and several blood flow signals (D) were seen at its edge. Three weeks after the infarction, the ultrasound showed that the echogenicity of the upper half of the left testis was reduced, measuring 15 mm * 16 mm (E), and several punctate foci with strong echogenicity (F) were observed. Five weeks after infarction, the ultrasound revealed heterogeneous localized echogenicity in the left testis, measuring 14 mm * 15 mm (G), and enhanced signals (H) appeared in the infarct after contrast
