Overview
Imaging studies for scrotal mass include scrotal ultrasound, MRI, and chest x-ray.[1]
Imaging
Scrotal Ultrasound
- Scrotal ultrasound is the imaging modality of choice for scrotal mass.[1]
- The sensitivity of ultrasound in the identification of scrotal mass is very high (100%).
- Scrotal ultrasound can accurately differentiate extratesticular and intratesticular scrotal mass.[2]
- On scrotal ultrasound, the epididymis appears isoe- to slightly hyperechoic compared with the testis.[1]
- The fact to be remembered before performing scrotal ultrasound is to rule out emergency conditions such as testicular torsion, where it would need emergent surgical referral.[3]
MRI
- MRI of scrotum is seldom used for the detection of scrotal mass, as ultrasound is inexpensive, highly accurate, and easy to perform.[1]
- MRI is particularly helpful in differentiating extratesticular solid scrotal masses (lipoma, liposarcoma).
- Findings on MRI suggestive of scrotal mass are tabulated below:[1]
| MRI component | Findings |
|---|---|
| T1 |
|
| T2 |
|
Chest X Ray
Chest x-ray may be performed to detect metastases of scrotal tumor mass to the lungs.
