Vasitis or inflammation of the vas deferens is a rarely described condition categorized by Chan & Schlegel1 as either generally asymptomatic vasitis nodosa or the acutely painful infectious vasitis. Clinically, infectious vasitis presents with nonspecific symptoms of localized pain and swelling that can be confused with other, more common conditions such as epididymitis, orchitis, testicular torsion, and inguinal hernia. Ultrasound with duplex Doppler scanning can be used to exclude epididymitis, orchitis, and testicular torsion. On the other hand, while inguinal hernia is difficult to differentiate from vasitis using ultrasound, computed tomography (CT) is diagnostic. We describe 2 cases of vasitis with clinical and ultrasound findings that initially were interpreted as inguinal hernias. In both patients, CT was diagnostic for vasitis showing an edematous spermatic cord and no hernia. Urine cultures in both patients were negative, but the symptoms resolved with antibiotic treatment.
First, the ACR Select software is a useful tool to assess appropriateness of CT and MRI, although it may underestimate the level of appropriateness of studies labeled as inappropriate. Second, CT and MRI are being ordered appropriately in Island Health in British Columbia. The software recommendation of MRI as more appropriate in 20% of cases where CT was done suggests a lack of MRI resources in Island Health.
A liver CT protocol with later arterial phase, faster injection rate, and weight-based dosing of intravenous contrast significantly improves liver enhancement and iodine concentrations in patients with cirrhosis, resulting in significantly fewer suboptimal studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
