Diagnostic Laparoscopy for Ovarian Tumor Due to Salmonella Infection

Ovarian abscess is thought to be caused by ascending infection. We experienced a case with ovarian abscess caused by Salmonella. The patient had been monitored for endometrial cysts at an outpatient clinic. She visited our hospital emergently with chief complaints of persistent fever and diarrhea. Although sexually transmitted disease was not suspected, she was diagnosed with pelvic inflammatory disease due to her high C-reactive protein (CRP) level and started antibacterial treatment. Two days later, diagnostic laparoscopy was performed for persisting CRP elevation, and she was diagnosed with ovarian abscesses due to Salmonella infection. As the patient had regularly eaten soft-boiled eggs and chicken, an association with her eating habits was strongly suspected as a cause. When a patient has symptoms of enteritis, preceding tubo-ovarian abscess should be considered the possibility of Salmonella infection. Early diagnosis and treatment are necessary for fertility preservation, and minimally invasive diagnostic laparoscopy is useful.
