Abstract

Actinotignum schaalii is an underappreciated cause of urinary tract infections (UTIs) in older adults. The diagnosis may be missed due to difficulty isolating and identifying the organism. Complications can result because the organism is intrinsically resistant to 2 commonly used drugs to treat UTI, as illustrated by this case.

Keywords: Actinotignum schaalii; chronic prostatitis; epididymitis; orchitis; urinary tract infection (UTI).

(A) Initial ultrasound image demonstrates enlarged and heterogeneous epididymal tail consistent with epididymitis (arrows). Several hypoechoic areas are also present (asterisks), consistent with abscesses. Doppler image showed increased vascularity of the left epididymal tail (not shown). Abbreviation: T, testis. (B) Follow-up ultrasound 6 months later demonstrates resolution of previous findings with a normal-appearing epididymal tail (arrowheads).
