testicular sarcoidosis
Testicular sarcoidosis is a rare manifestation of sarcoidosis. In cases of urogenital sarcoidosis, more commonly the epididymis is affected.
Epidemiology
Testicular sarcoidosis is more common in African-American patients, as are other forms of sarcoidosis . Up to 5% of patients with chronic sarcoidosis have evidence of testicular disease on autopsy .
Clinical presentation
Patients may be asymptomatic or present with pain or a mass .
Radiographic features
Testicular sarcoidosis should be considered in cases where there are multiple masses in the testis and epididymis .
Ultrasound
On ultrasound, enlarged epididymides and multiple nodules with decreased echogenicity can be expected .
MRI
Expected findings on MRI include :
- T1 C+ (Gd)
- enlarged epididymides
- may be unilateral and solitary, however, more often are multiple, small, bilateral nodular lesions
- enhancing with contrast
- T2: as above however lesions show low signal intensity
Treatment and prognosis
Excluding a testicular malignancy and preserving fertility are the main goals of treatment .
