Fatal Clostridium sordellii ischio-rectal abscess with septicaemia complicating ultrasound-guided transrectal prostate biopsy.

Clostridium sordellii is a Gram-positive spore-forming anaerobic bacillus rarely encountered in human infection. A case of C. sordellii ischio-rectal abscess with rapidly fatal septicaemia is described which complicated ultrasound-guided transrectal biopsy of the prostate, despite ciprofloxacin prophylaxis. Neither C. sordellii ischio-rectal abscess nor ischio-rectal abscess complicating transrectal biopsy have been reported previously. Judging from our experience and the reviewed literature, the addition of prophylactic anti-anaerobe drugs should be strongly considered until an optimal prophylactic regimen will be defined by randomized controlled trials.
