Vasitis or inflammation of the vas deferens is a rarely describedcondition categorized by Chan & Schlegel1 as either generallyasymptomatic vasitis nodosa or the acutely painful infectious vasitis.Clinically, infectious vasitis presents with nonspecific symptomsof localized pain and swelling that can be confused with other,more common conditions such as epididymitis, orchitis, testiculartorsion, and inguinal hernia. Ultrasound with duplex Doppler scanningcan be used to exclude epididymitis, orchitis, and testiculartorsion. On the other hand, while inguinal hernia is difficult todifferentiate from vasitis using ultrasound, computed tomography(CT) is diagnostic. We describe 2 cases of vasitis with clinicaland ultrasound findings that initially were interpreted as inguinalhernias. In both patients, CT was diagnostic for vasitis showing anedematous spermatic cord and no hernia. Urine cultures in bothpatients were negative, but the symptoms resolved with antibiotictreatment.

Adnexal Pathology

Pelvic pain presents a common diagnostic conundrum with a myriad of causes ranging from benign and trivial to malignant and emergent. We present a case where a mucinous neoplasm of the appendix acted as a mimic for tubular adnexal pathology on imaging. With the associated imaging findings on ultrasound, computed tomography, and magnetic resonance imaging, we wish to raise awareness of mucinous tumors of the appendix when tubular right adnexal pathology is present both in the presence of pelvic or abdominal pain or when noted incidentally. Tubular pathology such as uncomplicated paraovarian cysts or hydrosalpinx is frequently treated conservatively with long-interval follow-up imaging or left to clinical follow-up. Thus, if incorrectly diagnosed as tubular pathology, an appendix mucocele or mucinous neoplasm of the appendix is likely to be undertreated. We wish to clarify some of the confusion around nomenclature and classification of the multiple entities that are comprised by the terms mucocele and mucinous tumor of the appendix.

Primary hepatic carcinoma (PHC) is the one of the most common tumors and the common cause of cancer death in the world. Detecting PHC in its early stage by imaging methods may greatly increase survival rates of patients. Ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography/computed tomography are common imaging methods in the diagnosis of PHC. In this paper, the application of different imaging methods in diagnosing the primary hepatic carcinoma will be discussed.
