Vasitis is inflammation of the vas deferens. The symptoms may mimic those of inguinal hernia or acute scrotum.
Risk factors for vasitis:
(1) post-vasectomy (vasitis nodosa)
(2) urinary tract infection (infectious vasitis)
(3) urogenital abnormalities
(4) epididymitis
Clinical features:
(1) pain and swelling in inguinal region and/or scrotum
(2) inflammation along the vas by CT or US imaging studies
(3) exclusion of inguinal hernia and testicular lesions by imaging studies
Features seen on sonography (Yang et al):
(1) heterogenously hypoechoic appearance
(2) increased blood flow
(3) thickened vas deferens
