Questions and Answers

What is the primary purpose of testicular imaging in clinical practice?

To assess testicular volume and size
To identify tumors in the testes
To evaluate blood flow in the testicular arteries
To differentiate between acute torsion of the spermatic cord and epididymitis (correct)

Which statement accurately describes acute torsion of the spermatic cord?

It is often spontaneous in young men and associated with acute pain (correct)
It presents with gradual onset of pain
It typically occurs in older men
It can be managed with antibiotics without surgery

Why is it crucial to differentiate between testicular torsion and epididymitis?

Torsion requires immediate surgical intervention while epididymitis does not (correct)
Epididymitis is more painful than torsion
Epididymitis is more common than torsion in all age groups
The imaging methods for both conditions are identical

Flashcards

Testicular Torsion

Twisting of the spermatic cord cutting off blood flow to the testicle. It occurs mainly in young men and causes acute pain.

Epididymitis

Inflammation of the epididymis, a structure attached to the testicle. It is often caused by infection and causes pain.

Testicular Imaging

Imaging technique used to distinguish between testicular torsion and epididymitis. It involves injecting a radioactive tracer and taking images over time.

Patient Positioning for Testicular Imaging

The patient lies on their back with their penis taped to the pubic bone and the scrotum supported. This allows for optimal imaging access.

Positioning of Testes in Testicular Imaging

The testes should be positioned symmetrically in the center of the image for accurate comparison and assessment of torsion.

Study Notes

Testicular Imaging Purpose

Differentiates acute testicular torsion from epididymitis.

Acute Torsion of the Spermatic Cord

Common in young men.
Characterized by sudden pain.
Requires immediate intervention.

Imaging Procedure for Differentiation

Patient Positioning: Patient supine, penis taped to pubic bone, scrotum supported for imaging access.
Testis Alignment: Testes positioned symmetrically in the center of the image.
Dynamic Imaging: Series of images taken at 2-3 second intervals after a 99mTc-pertechnetate injection.
Static Imaging: Subsequent static images after the dynamic series.
