The clinical significance of laparoscopy in the differentiation of inclusion cysts from ovarian masses: A case report and literature review.

Introduction And Importance: Peritoneal inclusion cysts (PICs) are infrequently encountered cysts within the abdominal and pelvic regions, typically observed in perimenopausal women. They frequently pose a diagnostic challenge as they can be clinically misinterpreted as ovarian-related lesions, owing to their resembling clinical presentations and radiological features.

Case Presentation: A 30-year-old female patient without significant medical or surgical history sought medical attention for mild left lower abdominal discomfort lasting two days. Initial evaluation ruled out pregnancy, and further tests showed no abnormalities in her blood work. Pelvic ultrasound revealed a 4.5 cm cystic mass in her left ovary while her right ovary and uterus appeared normal. A laparoscopic ovarian cystectomy was planned. During the procedure, it was discovered that the mass was not connected to the left ovary but was, in fact, a peritoneal inclusion cyst. CLINICAL DISCUSSION: previous intraperitoneal surgeries performed within a timeframe ranging from 6 months to 20 years, intraperitoneal inflammation, pelvic inflammatory disease, peritoneal tuberculosis, leiomyoma, tubo-ovarian abscess, among others. However, the absence of these predisposing factors does not minimize the possibility of PICs.

Conclusion: This case highlights the diagnostic challenges and the value of laparoscopy in accurately identifying and differentiating such cystic cases.
