A contrast-enhanced (i.v.) 16-detector row helical pelvic CT scan was performed (Figure 2). Multiple Gram-positive cotton ball-like bacterial aggregates consistent with Actinomyces species infection were observed (Figure 2(a)). Postoperative endometrial biopsy and vaginal and cervical smears also revealed aggregates of Actinomyces species (Figure 2(b)).
