Infectious vasitis is an uncommon clinical condition that can mimic epididymo-orchitis, testicular torsion, or inguinal hernia. Previous cases have implicated the usual urinary pathogens, but unusual organisms have also been reported. The infection may occur with or without epididymal involvement and usually responds to antibiotics. Rarely, incisional drainage is required. Diagnosis can be made using ultrasound or computed tomography. We wish to report a case of infectious vasitis associated with the isolation of Chlamydia trachomatis.
