[Pelvic actinomycosis revealed by pelvic peritonitis]

Pelvic actinomycosis is an infection due to actinomyces organism associated with an intra-uterine contraceptive device. This infection is often revealed by an uni- or bilateral adrenal lesion. Lesions are sometimes more extensive and affect next pelvic organs: rectum, ureter, bladder. Diagnosis is often histologic with percutaneous biopsy or surgical biopsy (laparotomy or coelio surgery). Treatment is mainly medical with prolonged use of penicillin (6 months in severely cases). Surgery must be thrifty and conservative.
