Pelvic actinomycosis secondary to intrauterine device.

Abstract

Actinomycosis is a rare bacterial infection causing lesions and abscesses, often mimicking tumors. It commonly affects the cervicofacial, abdominal, and thoracic regions. We present a case of a woman with an intrauterine device (IUD) who developed an abscess and abdominal symptoms. Initial studies suggested a tumor, but biopsy revealed inflammation. Subsequently, she was diagnosed with Actinomyces Israelii infection, her IUDwas removed, and she was treated with penicillin, resulting in improvement. Pelvic actinomycosis is uncommon and often diagnosed late, often post-surgery, requiring combined surgical and medical treatment.
