they are the most common solid malignancies among males in 15-34 years old. The early and correct diagnosis of testicular neoplasm is helpful for prompt treatment of those patients. Ultrasound examination is recommended as the first-line imaging method for detecting and diagnosing testicular neoplasms
which can sensitively discover lesions with abnormal echogenicity in testicles. However
the diagnostic performance of conventional ultrasound in differentiating testicular lesions is limited. Contrast-enhanced ultrasound (CEUS) is a new imaging method in differential diagnosis of testicular neoplasm
with prominent advantages of good safety
high sensitivity in displaying microvessels and real-time imaging. This article reviewed the application and research progress of CEUS in diagnosing testicular neoplasms in recent years.
