Primary ovarian abscess in virginal young woman with huge endometriosis cyst: A case report

Rationale:Primary ovarian abscess which develops as an isolated lesion without simultaneous tubal infection is a rare entity. Ovarian abscess (OA) is a serious complication of pelvic inflammatory disease (PID) rarely seen in virginal girls. Early diagnosis and treatment are essential to prevent further sequela including infertility, ectopic pregnancy, and chronic pelvic pain.Patient concerns:A 19-year-old virginal girl who presented with abdominal pain and pelvic mass with no risk factors.Diagnoses:Laparoscopic surgery was performed to confirm a primary ovarian abscess in the adolescent virginal female with a huge endometriosis cyst.Intervention:Ovarian abscess with extensive intestinal adhesions was determined during the laparoscopic operation. Abscess drainage and postoperative antibiotic therapy cured the patient.Outcome:After the surgery, the CRP level on the day of discharge was 3.18 mg/d. The histological findings revealed a cystic tissue sample with the fibrous wall infiltrated by neutrophilic granulocytes, and ectopic endometrium, suggesting abscess formation in the ovary and endometriosis cyst.Lessons:Although primary ovarian abscess in an adolescent virginal female is rare, given the severity of outcomes following ovarian abscess, this pathology should be considered in the differential diagnosis of virginal adolescents with fever and abdominal pain.
