# What You Should Know About Vasitis: A Case Report

## TL;DR

This case report describes a rare instance of vasitis, an inflammation of the vas deferens, and highlights the importance of accurate diagnosis to avoid misidentification with other similar conditions.

## Contribution

The paper presents a rare case of vasitis in a 27-year-old man and emphasizes the need for increased clinical awareness of this uncommon condition.

## Key findings

- Vasitis was diagnosed in a patient with right inguinal and testicular pain, confirmed through imaging and clinical evaluation.
- The case highlights the difficulty in diagnosing vasitis due to its rarity and overlapping symptoms with other urological conditions.
- This is the first reported case of vasitis in the authors' city, suggesting a need for greater awareness among clinicians.

## Abstract

Even though infected vasitis is rarely reported in the literature, there are other diagnoses that share the same clinical signs, including testicular torsion, epididymo-orchitis, epididymitis, trauma, and incarcerated hernia. A 27-year-old man was brought to the emergency department by his brother with right inguinal and testicular pain for one day. The history was not significant with fever, lower urinary tract symptoms, urethral discharge, change in bowel habits, previous history of inguinal swelling, or surgical intervention. On presentation, the patient was vitally stable, and right infra-inguinal and inguinal vas deferens were tender and swollen; however, both testes and epididymis were normal, and no urethral discharge. Vasitis, or inflammation of the vas deferens, is an uncommon illness that Chan PT and Schlegel classified as either asymptomatic vasitis nodosa or severely painful infectious vasitis. Acute infective vasitis is a really uncommon illness, with only a few occurrences documented in the literature. However, the retrograde transmission of urinary pathogens such as Escherichia coli and Haemophilus influenza is thought to cause acute vasitis. Because of its rarity and ambiguous imaging findings, diagnosing vasitis can be difficult. Epididymitis, orchitis, and testicular torsion can all be ruled out with ultrasound and duplex Doppler screening. Inguinal hernia is difficult to distinguish from vasitis with ultrasound; hence, CT and MRI are more commonly used to confirm the diagnosis. Since this is the first occurrence in our city that we are aware of, it was reported. A few cases from Saudi Arabia have also been documented, and by doing so, we may raise clinicians' awareness of this disease and ensure that they can treat patients without making an incorrect diagnosis.
