Epididymo-orchitis and complications. a Epididymo-orchitis. Longitudinal color Doppler US in a 31-year-old with acute left scrotal pain and recent diagnosis of Chlamydia trachomatis. There is extensive hyperemia of the epididymal head (arrowhead) and testis (arrow) compared to the contralateral side (not shown). The patient’s symptoms resolved after treatment with doxycycline. b Scrotal abscess. Transverse US image of the left testis in a 59-year-old paraplegic patient with recurrent epididymo-orchitis and scrotal abscesses. The left testis is nearly replaced by a heterogeneous fluid collection (small arrows). In the medial aspect, there is a cluster of echogenic foci (arrowheads) which result in reverberation artifact/‘dirty shadowing’ (large arrow) due to a gas component. Cultures following surgical drainage grew Pseudomonas aeruginosa and Enterobacter cloacae. c Vasitis. Longitudinal US image of the left inguinal canal in a 46-year-old with left scrotal and pelvic pain. There is hyperemia of the epididymal head and spermatic cord (arrow) as it traverses the inguinal canal. Note the normal-appearing superior aspect of the testis (arrowheads). d Vasitis. Axial CT image of the pelvis (same patient as in part c) shows an enlarged and inflamed left vas deferens (arrows). The right vas deferens is normal (arrowheads). The patient’s symptoms resolved after treatment with Ciprofloxacin
