Introduction: Pelvic inflammatory disease (PID) is defined as an acute and subclinical infection of the upper genital system, including the uterus, fallopian tubes, ovaries, and ligaments. It can lead to various complications, such as salpingitis, endometritis, oophoritis, perihepatitis, peritonitis, and tubo-ovarian abscess (TOA). Case Presentation: In our case, a 22-year-old Afghan woman presented with generalized pain in the abdomen and pelvis, accompanied by vaginal discharge and fever, following 17 days of Normal vaginal delivery (NVD) and septic shock. She had no previous history of PID. Abdominal ultrasonography revealed a significant amount of free fluid in the paracolic grooves and pelvis, along with a perforated mass on the right adnexa. As a result, she underwent laparotomy and right adnexectomy. A 10-day course of meropenem and vancomycin was prescribed, and the woman was discharged with oral antibiotics. Conclusions: Tubo-ovarian abscess following NVD is a rare condition that can occur in patients with preterm premature rupture of membranes (PPROM) and episiotomy. Therefore, it is essential to prescribe antibiotics in cases involving episiotomy and rupture of the membranous.
