BACKGROUND: Vasitis is a rare condition that may be challenging for the clinical practitioner. Sometimes it is misdiagnosed as incarcerated inguinal hernia; thus, patients end up receiving unnecessary surgery. Compared with the traditional approach with only sonography, the more recent introduction of computed tomography in the diagnostic process has provided higher quality imaging and more detailed anatomy. Consequently, some urologists advocate the efficacy of computed tomography in the differential diagnosis of difficult cases.
METHODS: We present the case of a 23-year-old male who suffered from right inguinal pain and swelling. His scrotum ultrasound showed multiple tubular structure dilatation within the subinguinal area and no testis torsion. The initial diagnosis was a right inguinal hernia. Computed tomography supported that initial diagnosis, and we presumed the lesion represented a herniation of the omentum with mesenteric vessels. Since there was a suspicion of hernia incarceration, the patient underwent diagnostic laparoscopy, which did not reveal herniation, but only erythematous reaction and swelling over the right spermatic cord. Following a final diagnosis of vasitis, he received empirical antibiotic treatment and his symptoms entirely resolved.
CONCLUSIONS: Even though computed tomography can provide thorough imaging of the urogenital system, the contrast enhancement within vessels and inflammatory organs can still be misleading in the diagnostic process.
RéSUMé: CONTEXTE: La déférendite est. une maladie rare qui peut présenter des difficultés pour le praticien. Parfois, elle est. diagnostiquée à tort comme une hernie inguinale incarcérée; ce qui amène les patients à subir une intervention chirurgicale inutile. Par rapport à l’approche traditionnelle avec la seule échographie, l’introduction plus récente de la tomodensitométrie dans le processus diagnostique a fourni une imagerie de meilleure qualité et une anatomie plus détaillée. Par conséquent, certains urologues préconisent l’efficacité de la tomodensitométrie dans le diagnostic différentiel des cas difficiles. PRéSENTATION DU CAS: Nous rapportons le cas d’un homme de 23 ans qui souffrait d’une douleur et d’une tuméfaction inguinales droites. L’échographie du scrotum a montré une dilatation de multiples structures tubulaires dans la région subinguinale, sans torsion du testicule. Le diagnostic initial a été une hernie inguinale droite. La tomodensitométrie a confirmé ce diagnostic initial, et nous avons supposé que la lésion représentait une hernie de l’épiploon avec des vaisseaux mésentériques. Comme il y avait une suspicion d’incarcération de hernie, le patient a subi une laparoscopie diagnostique, qui n’a pas révélé de hernie, mais seulement une réaction érythémateuse et un gonflement du cordon spermatique droit. Après un diagnostic final de déférendite, le patient a reçu un traitement antibiotique empirique et ses symptômes ont été entièrement résolus. CONCLUSIONS: Même si la tomodensitométrie peut fournir une imagerie approfondie du système urogénital, l’amélioration du contraste dans les vaisseaux et les organes inflammatoires peut encore être trompeuse dans le processus diagnostique. MOTS-CLéS: Déférendite hernie inguinale incarcérée tomodensitométrie laparoscopie diagnostique.

BACKGROUND: Vasitis or inflammation of the vas deferens is a rare condition, and few case reports with computed tomography images have been published since 1980.
METHODS: A 50-year-old man presented with severe right inguinal and lower abdominal pain. Initial diagnosis at the emergency department was incarcerated or strangulated inguinal hernia. The computed tomography scan revealed diffuse edematous changes of right spermatic cord and vas deferens with peripheral fat stranding. Correlating with his clinical symptoms, signs, and imaging findings, the diagnosis of vasitis was made. We report a case of acute vasitis about the cause, symptom, pathogen, differential diagnoses, image findings, and treatment.
CONCLUSIONS: Although very rare, vasitis should be listed as one of the differential diagnosis for inguinal mass lesions. Cross-sectional imaging may be necessary to confirm the diagnosis and exclude differentials such as an inguinal hernia. Recognition of the characteristic image findings can help to make the correct diagnosis and avoid unnecessary surgery.

Acute vasitis is a rare infection of the vas deferens. Clinical presentation and disease rarity can cause difficulty in correctly diagnosing this condition. Adjuncts to aid diagnosis can be used that include ultrasound scan (USS) or computed tomography. We report a unique case of acute vasitis following vasectomy, reversal and subsequent re-do vasectomy diagnosed using USS.

BACKGROUND: Amyand\'s hernia is an inguinal hernia containing the caecal appendix. It is usually an intraoperative finding, although it can be diagnosed preoperatively with radiologic examinations, which would show a tubular structure inside the inguinal canal.
METHODS: A male patient presented to the emergency department complaining of abdominal pain in the right lower quadrant. He had been orchidectomized during his childhood due to cryptorchidism, and had been under antibiotic treatment a week before due to a suspected gonorrhoea. A small irreductible mass was found in the right groin. Blood tests showed leucocytosis and elevated CRP. A CT-scan was performed, reporting a tubular structure with a blind end entering the inguinal canal that seemed to be the appendix. Single-port laparoscopic exploration was indicated, and a right vasitis was found instead of an Amyand\'s hernia. After the operation, the patient explained that he had not taken the antibiotics for the gonorrhoea.
CONCLUSIONS: Untreated gonorrhoea causes ascendant vasitis and orchyepididimitis. In the present case, since the patient did not have testicles, the inflamed vas deferens mimicked the Appendix inside the inguinal canal. If the patient had told the truth about the untreated gonorrhoea, maybe the condition would have been suspected and no radiological examinations would have been performed, which subsequently lead to an unnecessary operation.
CONCLUSIONS: Presently, Amyand\'s hernia is more frequently diagnosed preoperatively than intraoperatively. However when an Amyand\'s hernia is preoperatively suspected, the possibility of a vasitis should always be ruled out in order to avoid unnecessary operations.
