A number of patients who have had vasectomies for contraceptive purposes are subsequently found to have spermatozoa in their ejaculate, having previously been azoospermic. This may be the result of vasitis nodosa, when spermatozoa released into the tissues at the site of section of the vas deferens elicit a granulomatous inflammatory response, within which epithelial cells from the vas deferens ramify and connect with those of the other portion of transected vas deferens such that continuity is re-established.

NGF-immunoreactive material was found by immunohistochemical procedures in cases of vasitis nodosa and prostatic adenocarcinoma.72 So far, this has not been confirmed by biochemical methods, but it is noteworthy that vas deferens and prostate may be sites of NGF synthesis in certain mammalian species.10,11,44

Vasitis is a rare condition characterized by inflammation of the vas deferens. It includes vasitis nodosa and acute vasitis [1]. Vasitis nodosa is more common; it is a condition of chronic inflammation caused by obstruction of the vas deferens. Acute vasitis is acute infection caused by urinary pathogens [1]. Patients present with pain and swelling in the groin, and have a broad differential diagnosis [2]. This can cause diagnostic dilemma and potentially unnecessary surgery. We aim to present our unique experience of ultrasound proven acute vasitis following vasectomy.
