Pelvic actinomycosis presenting with a rectal stricture: report of a case.

We present herein the case of a patient with actinomycosis involving the pelvic cavity, who presented with a rectal stricture. It is rare for this type of actinomycosis to be accurately diagnosed preoperatively, but a precise diagnosis, made using needle biopsy guided by computed tomography allowed for successful treatment by resection of the granulation tissue surrounding the rectal stricture through a transsacral approach.
