Tests and diagnosisBy Mayo Clinic staff
To diagnose a spermatocele, you'll need a physical exam. Although a spermatocele generally isn't painful, you may feel discomfort when your doctor examines (palpates) the mass.
You may also undergo the following diagnostic tests:
- Transillumination. Your doctor may shine a light through your scrotum. With a spermatocele, the light will indicate that the mass is fluid-filled rather than solid.
- Ultrasound. If transillumination indicates a fluid-filled mass, your doctor may order an ultrasound to confirm the diagnosis. If transillumination doesn't clearly indicate a cyst, an ultrasound can help determine what else it might be. This test, which uses high-frequency sound waves to create images of structures, may be used to rule out a testicular tumor or other cause of scrotal swelling.
