Reported here is a patient with pelvic actinomycosis unrelated to the use of an intrauterine contraceptive device.

The typical histopathological features of the Splendor Hoeppli phenomenon with sulphur granules and isolation of the actinomyces organism (which is rare) revealed the diagnosis of actinomycosis of the fallopian tubes. Pelvic actinomycosis is a rare condition and seldom described in the absence of an intrauterine device. High dose, long term antibiotic therapy is the key to successful resolution with surgery reserved for refractory cases. This patient showed good clinical and radiological response.
