Imaging of the scrotum

Area of Science:

• Radiology
• Medical Imaging

Background:

• Ultrasonography is the standard for evaluating scrotal lesions.
• Ultrasound can be inconclusive for certain scrotal pathologies.
• Magnetic resonance (MR) imaging provides supplementary diagnostic information.

Purpose of the Study:

• To review ultrasound and MR imaging features of scrotal lesions.
• To discuss imaging findings for both intratesticular and extratesticular conditions.
• To highlight nonneoplastic lesions that may mimic malignancy.

Main Methods:

• Review of ultrasound imaging techniques and findings for scrotal lesions.
• Review of magnetic resonance (MR) imaging techniques and findings for scrotal lesions.
• Discussion of normal scrotal anatomy and imaging protocols.

Main Results:

• Detailed description of imaging characteristics for various scrotal lesions.
• Presentation of features differentiating neoplastic from nonneoplastic conditions.
• Inclusion of acute and nonacute scrotal pathologies.

Conclusions:

• Ultrasonography is the first-line imaging modality for scrotal lesions.
• MR imaging is valuable for inconclusive ultrasound findings.
• Comprehensive understanding of imaging features aids in accurate diagnosis of scrotal conditions.
